I had a baby 13 days ago. At birth she was 6.8lbs and now at day 13 she is 7.3lbs. She is ebf. The midwife has just said she's not gaining weight quick enough. I worked out since her last weigh in she has been gaining 20g a day. Apparently a baby should be gaining 30g a day. Can't help but worry now that im doing something wrong. I feed her every 2 Hrs sometimes even less if she wants it. Has anybody got any advice what I can do to make her gain a bit more?
