Key Takeaways

There is a specific kind of frustration that hits around month seven. Your baby is thriving, the rolls are magnificent, and every pair of pants you own either slides off the waist or leaves a red ring around the thigh. The size chart says 9 months. The thighs say otherwise.

Chubby thighs are not a sizing problem so much as a fabric problem. Woven pants and anything with a fixed leg opening will pinch no matter what size you buy, because sizing up just gives you a longer pant with the same narrow leg. Knits do the opposite. They stretch across the widest part and settle back, which is why almost everything I pulled for this week’s Berry Basket is hacci, waffle, microfleece, or jersey.

The other thing that jumped out while I was working through this week’s baby deals: Modern Moments by Gerber is running discounts I do not usually see outside a holiday event, with several sets past 60% off and bestseller ranks under 50. Gerber’s own multipacks are more modest but steadier. Prices verified August 22, 2026.

Which baby pants have the most room in the thigh?

Multipack knit pants, every time. They are cut with a wide, soft leg and an elastic-free or covered waistband, and buying three or four pairs at once means you can size up without gambling a full outfit price on a guess.

These are the workhorses. Not exciting, but they are what your baby will live in from September through the first cold snap.

Gerber 4-Pack Microfleece Leggings

Four pairs of microfleece leggings in pink, gray and black, sized 3-6 months. Microfleece has more vertical stretch than cotton jersey, so it rides up over a thigh roll instead of catching under it. This is the pack I would start with if you are not sure what size fits, since four pairs at this price is cheaper than two pairs of most single leggings.

  • Four pairs in pink, gray and black
  • Microfleece with two-way stretch
  • Sized 3-6 months

Gerber 3-Pack Jogger Sweatpants

A three-pack of jogger sweatpants in navy and gray, sized 2T. The ribbed ankle cuff is the useful part here, because it lets you size up for thigh room without the hem dragging on the floor. Good for a toddler who is between sizes, which is most of them.

  • Three pairs, navy and gray
  • Ribbed ankle cuffs
  • Toddler 2T sizing

Gerber Multi-Pack Baby Pants

Gerber’s multi-pack pants in dark shadow, sized 6-9 months, and about as basic as baby clothes get. Plain knit pull-ons with a soft waist, meant for stacking in a drawer and rotating through the wash. If your baby is in that stage where two outfits a day is normal, this is the practical buy.

  • Multi-pack in dark shadow
  • Soft pull-on waistband
  • Sized 6-9 months

Huggies Waffle Knit Outfit Set

Waffle knit is having a moment and it earns it, because the texture has natural give in both directions. This Huggies two-piece pairs a crewneck sweatshirt with matching pants, and the waffle structure means the leg holds shape without clamping. One of the better fall-weight options in this week’s pool.

  • Crewneck sweatshirt and pants
  • Waffle knit with natural give
  • Two-piece matching set

Are two-piece sets easier than one-piece outfits on a chunky baby?

Usually yes. A one-piece has to clear the shoulders, torso and thighs in a single size, so a baby who is wide in the middle gets forced up two sizes and swims in the arms. A two-piece lets you mismatch, and nobody will notice.

Modern Moments by Gerber dominates this section because that is where the discounts landed. If sets are your default, the wider Gerber baby clothing roundup covers more of the line.

Modern Moments Honey Comb Knit Set

The honey comb sweater knit top with matching pants in medium green, 18 months, and the steepest markdown I found in this category all week at 71% off. Sweater knit has an open structure that gives at the thigh, which is why it works better than a woven pant for a chunky 18 month old. It also sits at bestseller rank #33, so the fit is not a fluke of one lucky reviewer.

  • Sweater knit top and pant
  • Medium green, 18 months
  • Bestseller rank #33 in baby

Modern Moments Hooded Hacci Set

Hacci is a lightweight double knit, softer than French terry and stretchier than jersey, and it is close to ideal for babies with rolls. This green heather hooded set in 12 months is ranked #8 in baby, which is the strongest sales signal in the whole group. The hood makes it a decent early-fall layer without needing a jacket.

  • Hacci double knit fabric
  • Green heather, 12 months
  • Bestseller rank #8 in baby

Modern Moments Fleece Pajama Set

A fleece sweater and pant pajama set in dark blue camp, 18 months, marked as a limited time deal. Fleece pajama pants tend to run generous through the leg, which is exactly what you want for sleep when a tight seam will wake a baby up at 2am. If you are still sorting out summer sleepwear, the lighter sleep sack options cover the other end of the year.

  • Two-piece fleece sweater and pant
  • Dark blue camp print, 18 months
  • Limited time deal

Modern Moments Wide Leg Pants Set

A sweater with wide leg pants in peach, 3T, and the wide leg is the whole reason it is here. Wide leg cuts skip the thigh problem entirely because there is no taper to fight, and they read as a deliberate style choice rather than a size-up compromise. Rank #95 in baby at 77% off is the best price-to-popularity ratio on this list.

  • Sweater with wide leg pants
  • Peach, 3T
  • No taper through the thigh

Modern Moments Henley Corduroy Set

A henley top with corduroy pants in brown, 3T, and the one caveat set in this section. Corduroy is a woven fabric, so it will not stretch the way the knits above do, and I would only buy it for a toddler who has slimmed out past the roll stage. As a fall photo outfit at 70% off it is hard to argue with.

  • Henley top with corduroy pants
  • Brown, 3T
  • Woven fabric, less stretch

What if the waistband keeps leaving marks?

Look for a covered or rolled waistband in organic cotton rather than exposed elastic. Burt’s Bees Baby builds their leggings this way, and the cotton is pre-softened so it does not stiffen up against skin after a wash.

This matters more than it sounds if your baby is prone to irritation. Parents dealing with that regularly may want the fuller organic cotton guide for eczema-prone skin.

Burt's Bees Tunic and Leggings Set

A tunic and leggings bundle in 100% organic cotton, currently a limited time deal at half off. The tunic length is genuinely useful on a chunky baby because it covers the waistband entirely, so nothing is pulling or gapping at the middle. Burt’s Bees sizing runs true but the cotton does shrink slightly on a hot wash, so size up if you are between.

  • 100% organic cotton
  • Tunic length covers the waistband
  • Limited time deal

Burt's Bees Baby Shirt and Pant Set

The boys’ shirt and pant bundle, same organic cotton, and the softest fabric hand of anything in this roundup based on the spec sheet and how consistently this line performs. Pants have a rolled waist rather than a banded one. At around a third of its usual price this is the easiest recommendation in the section.

  • 100% organic cotton bundle
  • Rolled waistband on pants
  • Top and bottom outfit

Burt's Bees Honeysoft PJ Set

Honeysoft lyocell pajamas, a tee with long pants, added to the deal pool two days ago and already ranked #39 in baby. Lyocell is cooler and more drapey than cotton, so these work for a house that is still running warm in late August but heading toward fall. Pair them with footless pajama styles if your baby fights anything on their feet.

  • Honeysoft lyocell tee and long pants
  • Cooler and more drapey than cotton
  • Bestseller rank #39 in baby

Frequently asked questions

What size pants should I buy for a baby with chubby thighs?

Go up one size from your baby’s age range and choose a knit fabric rather than a woven one. Sizing up in a woven pant only adds length, not thigh width, so the pinch stays. Joggers with an ankle cuff let you size up without the hem dragging.

Which fabric is best for babies with rolls?

Hacci knit, microfleece and waffle knit all stretch in two directions and settle back without leaving marks. Corduroy, denim and most twill pants have no give at the thigh seam. Organic cotton jersey works well too, especially with a rolled waistband instead of exposed elastic.

Are multipack leggings worth it over single pairs?

For babies in a growth spurt, yes. A four-pack costs less than two single pairs at full price and gives you enough rotation to survive laundry days. It also lowers the risk when you are guessing at fit, since you are not out much if one size runs small.

Do baby leggings shrink after washing?

Organic cotton styles like Burt’s Bees can shrink slightly on a hot wash and a hot dryer cycle. Wash cold and tumble low and the change is minimal. Microfleece and synthetic-blend knits hold their dimensions better through repeated washes.

Why do babies have chubby thighs in the first place?

Babies store fat rapidly in the first year to support brain growth and to regulate body temperature, and thighs are one of the main storage sites. It is normal and it evens out once they start walking. Clothing sizes just have not caught up to how much variation there is.

Discounts across this week’s baby clothing pool ran from about 42% up to 77%, which is wider than a typical late-August week. Modern Moments by Gerber accounted for most of the deep end, with the honey comb knit set at 71% and the wide leg pants set at 77%, and both carry bestseller ranks under 100. That combination is what tells me these are real markdowns and not an inflated list price, because a product ranked #33 in baby does not need a fake discount to move.

Honest read: this is a strong week for anyone buying pants, and an average one for everything else. The hooded hacci set at rank #8 is the one I would point a friend to first, with the Gerber microfleece four-pack right behind it for pure value per pair. I would skip the corduroy henley set unless your toddler has already thinned out, because a woven pant undoes the whole point of shopping for thigh room.

Watch the Modern Moments line over the next two weeks. Discounts this deep on stock this popular usually mean a seasonal changeover, and once the fleece and sweater knit sets sell through, the replacements will land at full price for the fall run. If you have been holding off on toddler sizes, this is the window. More of the week’s baby markdowns are over in the full deals hub, and if you are outfitting a new arrival rather than a growing one, the newborn outfit roundup is the better starting point.
