I have always been a big fan of Carter’s and love their onesies…but these are so much better. The material is incredibly soft and just the right weight. It’s obviously quality material but not so thick that it’s hot. We had these in size 0-3 month and my daughter just outgrew them at 6 months (she has been true to size in every other brand). The double snap feature made them last for a full 6 months! We were able to completely skip size 3-6 month and just bought the 6-9 month size in both white and multi-color. I fully expect her to be able to wear these until at least 11 months. I can’t recommend these enough. They hold up to repeated washing and maintain color and shape...she’s in them almost every day. We also have the pants and hoodie with grow cuffs and she’s still wearing the 0-3 month sizes in those…again, she runs true to size in all other brands.
