    We LOVE Little Sleepies!

    These are great, light weight and plenty of stretch for a growing toddler!

    These are amazing!

    My son is obsessed with construction vehicles and his birthday is coming up, so this was perfect for him. He loves them so much he didn’t want to change out of them. They’re soft, comfortable, and fit true to size!

    The BEST!

    We love all our LS jammies but we are partial to the shorts sets! These are absolutely adorable and my son is obsessed! He’s 4, in a 4T and I ordered a 4! They fit well with room to grow!
