It was so nice to find pants for my son in colors other than blue and grey. The pants are light weight (important in the TX heat) but feel sturdy enough to handle crawling all over the place. They are the first pants we've found that are not too long but still have some room around the waist. We purchased size 12-18 months and are happy with the fit (he's 31" and ~24lbs). It's hard to know how sizes will fit my little guy because he's just 9 months old but is big for his age, so the extra room in the waist may give us room to grow a bit in these verses some of the more expensive items that get worn a few times then are too small to be comfortable.I purchased 4 pairs of these pants in various colors and would definitely consider buying more. Keep in mind if you have a skinny-minny kiddo, you may need to put a few stitches in the waistline to pull them in a bit. But for the price, it may be worth the few extra minutes that would take.I bought these in 3-6 months for my 12 week old. He's a big boy, 14.5 lbs. 25 in. (bigger than 75% of babies his age as told by his pediatrician). He usually fits this size perfectly, However, these are pretty big on him. The waist is much too big and the legs are too long. I will note that his legs are not very long so they might fit better on a baby with longer legs. These are 13 in. long and 8 in. wide. So I just rolled them in at the waist twice and it doesn't look too bad. I'm actually happy that he has room to grow in them because I do love the deep, army green color. Arrived on time. I'd recommend!Fits short fat babies. Appears to be nice quality, lightweight, simple pants which is what I was looking for. My child is short, normal weight with a Buddha belly. He'll be 24 months in a couple of weeks and the 18-24 mo pants would literally fall off of him when he walked. If they stayed up, I think they would have been a little on the short side - not typical, as all other 2T pants are 2-3 inches too long for him. It would have to be a pretty large wasted child before the elastic in the waist would do any good. Too bad, b/c otherwise they would have been great.I love everything about these pants. We've been buying them in multiple colors for my son since he was wearing the 3-6 month size and I'm about to the purchase 12-18 month size.They fit great, hold up well in the wash, and I love that there are more color choices that just blues/gray/black in pants that boys can wear. He looks adorable in the purple pants with his Hulk onesie!So, I ordered 12-18 months for my 15 month old average size son. When they came in the mail, the tag on the pants just said 12 months, not 12-18, and they fit like they were maybe 9-12 months. He still wears them, they're cool, but they're kinda short on him. As far as quality, the pants feel good. They are not thick how they looked (to me) on the picture. They are a thin. Breathable material. I got the brown, and would like them a lot more if they were long enough but whatever, they're okay 3 starsThese pants are awesome! Super comfortable and the waistband is soft and stretchy. I have the hardest time finding pants for my infant son that aren't too tight across the belly. He's a pretty chubby 3 month old and is already fitting into size 6 mos. clothing. I have tried many brands and have found that so many of the waistbands are just too darn tight! But these pants are excellent and allow him to trench his legs and move while staying up! They are not restrictive at all and don't squish his tummy. Perfect!I love these. Not a huge fan of the waistband, which feels a little cheap. These feel more handmade than they do factory made. They are fairly soft and thick enough for cooler weather but not so thick that they couldn't be worn in warmer weather as well. The length is similar to Carter's pants and the black is really dark and true. I hate having to deal with buying pants to match onesies that aren't a part of a set, so I bought these and a pair of jeggings for her so everything would match. It was perfect for us.My son is 6months but really long and grew out of all his pants..I tried these because the price was great and so far so good..I love the comfortably and lightness of material. Not sure how there gona wash up scared their going to shrink like the rest but hopfully not..depending on the length of your child don't think they will fit him at 12months.
