DD is a month old. I read the books. Some things you just have to learn on your own. Feel free the share yours too.
1. When bathing baby in the sink, make sure the spout isn't over her head. That way when you're done with the hose you don't almost drown your baby.
2. When removing clothes your DH/SO dressed her in that day, check for buttons BEFORE pulling garments over babies head. That way you're not trying to remove buttons with the garment stuck around your irritated baby.
3. Even baby girls will pee when the diaper comes off.
