My daughter is 13 days old and lost 10% of her birth weight. She’s formula fed. She put on some weight but now is static and hasn’t gained any. She’s a pain to feed, only takes an ounce or so at a time every 3 hours. She’s very sleepy and we wake to feed. She’s on baby gaviscon for reflux and Dr Browns bottles. She has plenty of wet and dirty nappies but won’t drink anymore. So, she’s drinking enough to keep her full but not to gain any weight. I can’t force it in her and feel awful and like a rubbish mum. My son was the same and very slow to gain weight while being formula fed but my stress levels are through the roof and im dreading every feed. Anyone else had this issue?
