How old was your LO when they hit it?
Bean is 15 days old and for the last day has been very fussy, latched on and off and just generally had issues. She was born a month early and her latch is awful but we are working on it... I don't think that's it. No excessive gas, plenty of dipes and otherwise fine - just fussy nursing. I nurse her on demand and she's been pretty much attached to me every hour for the past 24. Truth be told I kind of like it. I love holding her : )
so maybe growth spurt? I hope not, I don't want her to grow up!
