My baby girl had a doctors appointment yesterday and they said she hasn’t gained enough weight from the last time we were there! They said she needs to start gaining weight. I told them I’m feeding her like I’m supposed to but she sleeps a lot so it’s really hard for me to get her to take a bottle! (Also she is formula fed) The doctor said she need to gain weight before her next appointment which is next week. Should I be worried? What can I do to help her gain weight?’
