Re: Spitting up and gagging only at nigh
You might want to try feeding her in a position where you are more reclined. A lot of moms have more abundant milk at night, particularly when their babies start going longer at night between feedings. If you are flooding your baby with milk, that could cause the gagging and spitting up- so using a position that takes advantage of gravity to slow milk flow could be beneficial. You also might want to try burping her in between breasts, or even partway through a single breast.
