Q: When can I put my baby down to sleep and go have a glass of wine?
A: Jennifer Waldburger, L.C.S.W., co-owner of the Los Angeles-based consultation service Sleepy Planet, and other experts suggest that when he's about 5 months old, you can experiment with letting your baby cry a bit at night. (That does not mean letting him cry it out for hours.) Try starting with five minutes, Waldburger suggests; if that's too hard to take, pick him up after three minutes. "It sounds cruel not to pick up a crying baby," she says, "but we find that teaching babies how to calm themselves is really kinder in the long run. We suggest a long wind-down period with lots of cuddles and laughs, comforting with your voice and finally letting the baby soothe himself to sleep."
