Be prepared. When you've got small kids, getting woken up in the middle of the night can be more the rule than the exception. Moms should really expect that they will be woken up every night and plan accordingly. They need to get to bed early enough to accommodate it.

Take naps. Although sleep experts advise against naps for most people with insomnia, they say sleep-deprived mothers should ignore that advice. Nap when your baby naps, if your kids are still young enough to nap themselves.

Catch up on sleep during the weekend. Use the weekends to atone. Swap time with your spouse on weekends so that you can both sleep in one day. Or try to make a standing appointment with a relative or sitter to get a couple of hours of nap time during the weekend.

Help your child sleep more soundly. It takes at least three to six months before babies adopt a sleep schedule that's even remotely civilized. But if your older children have a consistent problem sleeping through the night, you might want to talk to your pediatrician.

Relax before bed. Bedtime rituals are important for everybody, not just toddlers. So don't try to go straight from washing dishes or checking email to bed. Instead, dim the lights and read for a while or pray. Building in a little time to unwind before getting into bed.
