Most new parents think they don't need to worry about things like outlets until their child is mobile. What they don't realize is how fast that day will arrive. Your child will start rolling, long before you're ready, and crawling will begin shortly thereafter. Once the walking is in full effect, forget it. So, even though your child is still a newborn and peacefully still at the moment, it's best to go ahead and cover those unused electrical outlets with protective inserts. It may seem premature, but before you know it, your baby will be crawling around with a desire to stick those sweet little fingers in places they shouldn't go. Installing the caps when you finish your nursery will get you and your baby used to them being there, so when the time comes, they'll discourage prodding fingers.
