she should be ok as long as she getting the breast milk. what stage food are you trying to give her? have you tried just plain baby cereal? if you can get her to take that then mix i little bit of friut or a veggie in it. also they do sell a mess teether that you can put fruits or veggies in so she can chew the heck out of them. as for the waking up at night maybe try to cluster feed her in right before bed say like if she eats dinner at 6 nurses at 7 and bed at 8... try feeding as much of the solid you can get her to eat then have her nurse about 30 mins earlier then you would and then a half hour before she would goto bed try to get her to nurse again. i hope this is helpful to you! just give it time
