4. Need: Activity Mat
To balance out any time spent in a car seat or swing, provide your baby with plenty of floor time. An activity mat is a great way for an infant to explore and practice skills like reaching, grabbing, and stretching. A brightly-colored mat with dangling toys and a mirror will make that all-important daily tummy time a whole lot more fun.
