I've been reading reviews here on the Gerber onesies and I just feel like I need to stick up for them. My review is geared especially towards those who have preemies or babies who run low on the growth chart. It is like the designer of these onesies had a preemie themselves and were sick of others on the market.

I am the mother of a preemie 17 month old who was 2lbs, 7oz when born at 31 weeks, and growth restricted. She is 25th percentile for height and <3rd for weight now...so she is thin and tiny.

The Gerber brand onesie is all I buy. They've always fit her great, and when you find something that works so well on your child you stick with it. I will be the first to admit that Carters is so much softer, but I don't feel like these are irritating to her skin or uncomfortable for her, and therefore a reason not to buy them. In New England winters, you have to layer up--no baby belly hanging out, so you must have a lot on hand to put under her clothes. They are so slim-fitting and thin that they fit perfectly even under the snuggest of shirts.

Sizing is very, very small...my lil gal is moving into the 24 month size...which is the only time right now she'll touch a 24 mo size! :) ALl other reviewers are right, buy 1-2 sizes bigger even if you think it is weird to do so: "My 20 lb 8mo old would NEVER fit into 18 months!". This is the best advice anyone can give you about this brand. Buy big--trust me, its tiny and shrinks.
