Educational and interesting toys need not be purchased. Take a cylinder, such as an empty paper-towel tube, and show your baby how objects can pass through it. Place it upright on the floor and fill it with several objects and then let her pick the tube up. Watch in delight when they all fall out. Of course, it's always important to stay with your baby when playing, especially with small objects.
Keep iron supplements, as well as all medications, out of your baby's reach. As few as five tablets of a high-potency preparation could be fatal to a 22-pound child, according to the FDA Consumer (May 1993). Don't be lulled into a false sense of security by child-resistant bottles.
