Re: Lazy latch and very distractible baby..Lowered milk supp
Aw, mama! Sorry you're having a tough time! I hope it will reassure you if I say that what you describe sounds pretty normal for this age. Being distractible: normal. Faster feedings: normal. Baby acting frustrated once letdown ends: normal. Supply down a bit compared to the first couple of months of nursing: normal (milk supply tends to be most abundant in early infancy, and then adjust to match baby's demand very exactly).
You're right that weight gain typically does not slow until the 4-6 month window (see: http://kellymom.com/bf/normal/weight-gain/) but high active babies sometimes slow down a little earlier.
Just checking- any chance of pregnancy? And what form of contraception are you using, if any?
If you could post a complete weight history- birth weight, lowest weight, weight at each checkup- we might be able to reassure you a little more.
