Please help if you can. My DD is 3 months, has been an absolute angel the past month after some up and downs. A few days ago she stopped her normal napping (at least one long nap about 3 hrs. and the rest being an hour or so) and will only sleep a short time and then wake up. At least once a day when I am going to nurse her, she just opens her mouth wide and won't latch on, just screams and cries and then acts like she's choking.
I am just at a loss as to what might be the problem!
