Just had to update...we are now back to nursing at 1 am and again at 4 am. LO is nursing a lot, like 10 x a day! And often taking both sides and she isn't pooping every day! We are either growing or teething - or maybe both, but LO is very happy these days, so I can't complain. She is changing lots too developmentally in the past few weeks.
It really amazes me just how much babies can switch up their routine on ya! I can't imagine trying to schedule a baby at all at this point.
