My LO is now 4 months old and I'm a little worried about her weight gain rate and if she's getting enough to eat. At her 2 month appt, she weighed 11.5lb and now at 4 months, she's 12.9. We bought a scale last month and it seemed to bounce between 12.5-13lbs. At her appt this week, her pediatrician didn't seem concerned since she seems content after eating, has plenty of wet diapers and appears to be nice and healthy. Her weight puts her in the 20-30th percentile and her doctor said she might just be a leaner baby. She asked me some questions about nursing, but I still felt a little uneasy afterwards. She suggested a few things if I was concerned like pumping after a session to see if I express a lot to get an idea if she's eating enough, but I wasn't sure if that was an accurate way to tell. She's also not taking a bottle.
For the past month, she has been nursing for a short amount of time. It went from 6-10 minutes on each side to about 2-4 minutes now (sometimes only 1 minute on the right breast). It seems like she drains it in that short amount of time because the sucking noises and motions change and she pulls off. Is that possible for her to drain my breast so quickly? With the slower weight gain rate, I worry she's not getting enough milk. I feed her on demand (usually 2-3 hours) and she does seem content afterwards, sleeps 6-8 hours at night and has a lot of wet diapers.
Please let me know your thoughts and if this all seems fine or if you all think I might be having some issues.
Thank you so much. I really appreciate it!
