You are the only one that can protect your baby here are a few tips:
Don’t post baby announcements on social media or post a stork on your lawn.
Never leave your baby alone on a bed or changing table, they can fall off and get seriously injured.
Do not let anyone hold your baby unless they wash their hands first.
Never let sick people/kids around your new baby, they have an immature immune system and can get very sick.
Minimize visitors in the hospital so you can rest and get to know your baby. Take advantage of all the valuable information your nurse will teach you regarding taking care of yourself and your baby when you get home.
