S.H.
i wouldn't worry unless your doctor is worried. is she growing tall? My daughter was 97% weight and 97% for height around wbirth and is now 95% height and 36% weight. She is very healthy and active like yours. Laso if you are short, well be aware that that curve is based on a bunch of white folks in Utah. Generally tall people. Maybe she was born really chubby? Did she come out late?
I would start getting creative with ways to feed her. She will probably not gain any weight until she starts eating solids because she is already 7 months. Mix mango with the cereal. Put the cereal away and hand her a banana. Dont push her, let her explore the food herself. I got mine to eat the mushy bland baby food for a while, but she was never interested much in eating until we gave her what we were eating. Steam up some carrots really well, give her a piece of bread and see if she gums it down. hint: that food in the jars and boxes isnt really very yummy. Dont think kids need bland food. There are cultures in africa that start babies on Beef. In parts of Asian, a common first food is the radish.
