Thank you Ali & all who offered advice...we went to see the pediatrician (as Brinn developed bronchitis). She is getting all 4 molars at once right now. So the teething, combined w/a possible GS and the stress she must be sensing off of me re: our cross country move...I'd say it might be tricky weaning.
In the last week, she has actually done fine with just the 3X daily (morning, nap, night). I got her to nap w/o BF first, thankfully, so we're heading in the right direction.
