For about a week now my 9 mon old daughter has been very uninterested in nursing and when she does eat she eats for a very short time. I have tried laying down to feed, rocking, dark room, etc. Nothing really seems to make her more interested. She seems to be too distracted or simply not hungry. I have expressed milk and given her a bottle (she has been taking bottles/nursing since 11 days old-no problem with nipple confusion) and she shows the same disinterest. I am starting to be concerned about her weight. At her 9 month checkup 10 days ago she weighed 16 lbs and was 27 in long. At her 6 mon appt she was 13 lbs and 25 in long. She has always been in the 20th percentile since birth. We visited a new pediatrician at the 9 mon apt and he did not give me the percentile she was in but said she was incredibly healthy. When I got home I looked up her percentile and she is in the 5th percentile for weight. So that concerned me since its such a big drop in percentile. She's very active, very happy and she eats solids fairly well. She has no other issues other than the drop in nursing. I did eliminate her night feeding at 10:30p because she was not nursing for that one. So now she nurses 4 times a day. Normally for 10-20 min. Now it's closer to 5 min total. What can I do for her to help her eat more/gain weight. Or is there nothing to be concerned about?
