My daughter is 9 weeks (3 weeks adjusted) and gained weight like a rockstar over the last two months. She was 4 pounds 2 ounces at her lowest in the hospital and was 8 pounds 8 ounces at her two month check up on Friday, 4/27. She got her first round of vaccines then, and was not at all into nursing for 3 days after, so she lost about 2 ounces (I have a nursing scale at home). I pumped to keep up my supply, so that's likely not an issue. One week after her appointment she only gained 5 total ounces, whereas she used to gain about 10 ounces a week.
She went from nursing about every 3-4 hours and filling herself up and seeming very content after a feed to nursing now every 1.5-2 hours and doing more "snacking" type feeds. If she pulls off the breast she will NOT re-latch no matter what I do, and will start screaming for the next 30 or so minutes until she exhausts herself, falls asleep, and then wakes up an hour later to start the cycle over. She wets 6 diapers and has about 2 poops a day.
What is she doing? Why the change in nursing behavior and the less-than-stellar gain over the last week. What happened to my nursing super star? I'm going back to work in 3 weeks and this has me very nervous.
