    So soft! The only Pjs that my son will keep on!

    Baby girl loves these!

    Being that we live in FL I love how thin these are!! The zippies are our favorite!! I also love the fact that these don’t look like pjs to me like they’re actually cute and I don’t feel bad for leaving my girl in them all day!

    Perfect Jammies for my sweet boy!

    These pajamas are the best! I’ve become a Little Sleepies Snob but in the best way! My little boy has eczema and loves to scratch his head and neck to fall asleep! No matter what we did he wouldn’t be deterred from it. These pajamas allow me to cuff is hands and feet while he falls asleep and then when he is awake I un-cuff them. They are so soft and have the best designs and feel so good on his skin, I’ve noticed a drastic improvement in his skin! He also is 10 months (preemie) and wears 9 month clothing, but these have such good life to them and longevity that he can still wear 3-6. Waiting eagerly for the Toy Story sets to be filled to order! I will always buy these for my baby! Worth every penny!
