Re: Dropping percentile points on growth chart?
Whether or not your kid's pediatrician will have issues with her weight gain depends on your pediatrician. I think my pediatrician would probably be okay with it- both my kids dropped percentiles at their 4 month checkups, and all she did was nod and say "look, she's doing that thing all my breastfed babies do- leaning out". They both went from about the 95-100th centimes for weight to about the 75-80th- a bigger drop than what you're seeing, but starting with a much larger baby so of course there was less concern.
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
Coolest thing my little girl sang recently: "I love dat one-two pupples!"
