I gave these pajamas a lot of flack a while back for being a little pricey ,but I must say, they are worth it. My daughter just turned 6 months and is still wearing the 3-6 month size , and has a bit of room to grow. For prime day, I purchased her some 6-12 month sizes so she can have them when it’s time to size up. LTKBaby LTKKids LTKSaleAlert
