Sleep is hard to come by when you bring home a new baby. Even if you are bottle feeding your baby will be awake every few hours for 6-8 weeks. There is no way around this, in fact if your baby is not waking to eat you will want to set an alarm until they have beefed up a little bit (consult your doctor of course).
Sleep is essential to life and without it you are literally impaired. Before I get into my personal top tips I will share what everyone shares: sleep when the baby sleeps. I hate that advice even though it is 100% accurate because I always feel like I have too much to do. It is a cliché for a reason though.
