How much attention should I pay to the weight growth curve/percentiles, and how do I know that my daughter is gaining weight appropriately? My 10 week old bounces around between the 30th and 40th percentiles. I take her to a lactation support group each week and weigh her on the hospital-grade scale. My pediatrician seems satisfied with her growth, but I worry when she drops from a higher percentile to a lower one. There are a couple reasons I’d like to make sure she’s gaining appropriately: firstly, she is a very slow eater (45-75mins/feed) and the lactation consultant suggested I cut her off after 15mins/side IF she is gaining well. Also, we have just started trying to have Dad give her a bottle of expressed milk as her last feed- she will only eat 1oz and then fussed and refuses it, but then she goes to bed much more easily than when I put her down (which requires nursing her for more than an hour). I’m not sure whether it’s ok for her to have such a small feed and if this could further affect weight, or if she will naturally just make up the difference during other nursing sessions.
