Getting into the habit of having something to drink each time a mother sits down to pump is a good way to ensure she has adequate fluid intake. It is best to limit daily intake of caffeine-containing drinks since excessive caffeine can cause some babies to be wakeful. A young breastfed baby usually needs to nurse every 2-3 hours. It is best to pump on the same schedule. The more the breasts are stimulated, the more milk is produced.
Mothers can feel free to sleep a longer period at night.
Relaxing and realizing that the pump is a friend is the most important thing a mother can do. Watching the milk collection bottle is not helpful. Baby needs to get to know the breast as a warm, wonderful place to be. Expectations need to be realistic. Baby will start nursing gradually and gain skill with practice.
