Water babies Happy Nappy (size L) & Baby wrap (size L) I used these for my baby when he was age 4-8 months even though the wrap says it's size 18-30 months it's very small fitting & is easy to wear tighter. -Opens completely flat for easy dressing -Allows for baby to grow and can be adjusted to fit -Best core body warmth, leaving legs and arms free to kick and splash without restriction
