Ugghhh I'm trying to find my baby this elephant costume for Halloween and they don't have her size. She's 6 months but still wears a 0-3 months and the 6 month costume is huge on her, I can fit like 3 babies in there with her and still have room...😢😢😢😢 I want my baby to be an elephant so bad, its the cutest thing ever.
