We had an appt yesterday and she has gained 5.5 oz in ~6 days. That is "normal" weight-gain, but we were really hoping for some over-and-above gain so she could start catching back up. So, really good, but could be better. No blood in the stool, so unlikely that its any sort of allergy or intolerance (yay! This momma is having some ice cream today!). The IBLCL observed a feeding. We both agreed that when she initially latched on, she was hungry and excited to nurse and at the start appeared to be nursing well. She even commented that she could hear her swallowing from where she was sitting - all great stuff. Baby fell asleep and we weighed her again. Baby only transferred 0.5oz. We woke her up (and pissed her off a little, to make sure she was really awake), and latched her back on. This second time, she was noticeably more squirmy, arching her back, popping on and off. Again, she only transferred another 0.5oz before falling asleep.
I know it's only one feeding and we need to do it a couple more times to get a better picture, but all this together seems to make it more likely that the tongue tie is getting in the way. We have an appt in 2 weeks to have it lasered.
In the mean time, we're trying another experiment. Over the past week, we did two things: switch out bm for formula and switch out one nursing session in the evening for a bottle (because we were giving formula). So, we can't say for sure if the weight gain was due to the formula...
