I've been using the little pillow from the infant insert under DD's butt, but I'm wondering how to know when I can stop using it. She's almost 6 months, but just a bit small for her age (as of her 4 mo visit). I don't frog-leg her legs anymore, and without the pillow the edge of the Ergo hits right at her knee crease. She can just barely dangle both legs out and I can still kiss the top of her head without it. Any advice?
