2. Got a newborn? Nix trips to the shopping mall.
Experts agree that it's a good idea to limit where you take your baby during his first weeks. While a stroll in the park is fine, a trip to the mall is not. That's because newborns can easily pick up a bug when exposed to large numbers of people in a confined space. To be safe, keep her away from crowded places—especially those with lots of kids—for the first four to six weeks.
