24/7 gives tired a whole new meaning
No one is truly prepared for new-parent fatigue. Being available 24 hours a day, 7 days a week, is a grueling schedule. Newborns need around-the-clock care, and many infants seem to prefer to be especially active between 1 and 4 AM, a time when you may not be your perkiest. This is not the time to be shy about accepting help.
If this child is your first, rest whenever the baby sleeps. If you are formula feeding and have a partner, consider taking shifts. If both of you are up for every bottle and diaper, you will expire in stereo.
If you are breast-feeding, try to get help in between feedings, so you can take a nap. You won't see 8 hours a night for a long time, so you have to learn to catnap.
If you have another child who is home with you during the day, keep special toys or videos for times when you need the additional help and rest and can't give her your full attention. Consider an indoor picnic: spread an old tablecloth on the floor, and let the older child sit and watch a video while she eats. When it's done, just shake the tablecloth outside for easy clean up.
If you don't have an answering machine, now might be a good time to get one. That way you won't be disturbed every time the phone rings. Otherwise, consider shutting off the ringer when you're resting. Even if you don't sleep, lying on the sofa with your feet up and listening to soft music can allow your body to rest and recuperate a bit.
