Hello girls... We're on GVB. I wake up so often at night and my breast feels heavy? I used to sleep from 11 am to 3 pm, the rest of the time I tossed and turned. Now it sleeps for the first 40 minutes, but then...ppz. It turns, takes the breast, then spits out, can't fall asleep without titty, it turns away, turns back, grabs ???? damn. What is this shit?? Is GVB? Do they sleep better on formula?
