Never heard of a baby shower for a 2nd or 3rd baby. In our circles, people might have a baby-welcoming party of some kind, with belly casting, good food, friends, and well wishes. For our 3rd child, a friend organized a party where people donated a casserole or some kind of food that would freeze well. We filled our chest freezer. Then, the first few weeks after he was born, we didn’t have to do any cooking.
