I am the first time mom of a 5 1/2 week old boy. He was 8 lb 13 oz at birth, lost 10% in the hospital, but was back up to 8 lb 14 oz at his 2 week appointment and shot up to 10 lb 13 oz at his 4 week appointment.
Because of the initial weight loss and the fact that he kept falling asleep while feeding, I initially tried to make sure that he was feeding about 15-20 minutes per breast at first. Over the past few days, a couple of things have happened. One is that it is rare that he does a 20 minute feeding. He seems to be able to drain me more efficiently, and either he falls asleep and will not wake to feed any more (despite tickling, diaper change, wet washcloths, etc.), or he turns away and makes it clear he is done. The other issue is that he now seems to be satisfied with one breast only, which is difficult in the middle of the night when I do NOT have the energy to pump. Sometimes I can get him to wake up and take the second breast, but this is getting increasingly difficult - he just does not seem interested in it.
He is peeing and pooping normally and seems otherwise happy, though he's also been sleeping a bit more over the past couple of days than in the past. It is like he finally got the memo that many newborns sleep up to 16 hours per day - he was not a big fan of daytime naps up until a couple of days ago. He is still figuring out the spacing between feedings - generally every 2-4 hours and the shorter time does not seem to coincide with a shorter feeding prior to that.
So, a couple of questions. First, is this change in behavior normal? Do babies get more "efficient" at eating over time? Should I be trying to get him to take the second breast or do I then run the risk of overfeeding him? Is it even possible to overfeed, or will the baby self-regulate? Aside from the obvious engorement issue, am I at any risk of hurting my milk supply if he only eats from a particular breast at every other feeding?
I would very much appreciate any thoughts or help anyone can provide!
