Growth spurt

Growth spurt, which often happen at fairly predictable ages - around two to three weeks, six weeks and three months. Some experts think a growth spurt has two purposes -- to provide the baby with additional calories needed to grow and to adjust the mother's milk supply to meet the increased demands of a larger baby. It is also reasonable to think that babies, like older children and adults, may simply feel a greater need to eat on some days than on others.

So what to do during a growth spurt? Nurse, nurse and nurse some more! Breastfeeding works on a supply and demand basis. The more frequently a baby nurses, the more milk the mother's body will make. During growth spurts it is especially important that babies be nursed as often as they want. In fact, more frequent, shorter nursings build a mother's milk supply more effectively than infrequent, but longer nursings. Younger babies generally nurse more frequently than older babies because their stomachs are smaller. Nursing as often as twelve times a day is quite normal for the first few weeks.

So as long as there are no other reasons for it - baby is not sick or teething, for example, it is totally nomal, Summer went through it as well...

About the second issue, Summer doing the same thing sometimes, I think that is totally normal, just some kinds of Baby's Reflex Actions... As long as the bowl movement is normal, then it is fine....
