So my daughter just had her 12 mo check up and her doctor is concerned with her growth, as I knew she would be. She’s 15ib 14.5oz, 26.5 in. I keep all of her summary’s from all appointment’s and she was 15.9 ibs back in August at her 6 mo check up. I breastfeed exclusively and that’s seriously he only thing I can get her to take. She never ate baby food, I tried to give her everything from the fruits to the savorys, I’ve tried puffs, whole milk, eggs, pancakes, formula, everything I eat and no success. The only things she has showed interest in is applesauce (she still eats it but not as interested as she was she’s starting to push it away) and French fries (which she doesn’t like any more). Idk what to do, her doctor seemed worried at her appointment and of course I’m stressing out trying to figure it out because when I take her back in 6 weeks if she hasn’t grown, idk what’s going to happen. Anyone ever been through this?
