Brushing His Hair or Teeth
8 to 10 months
Imitation is one of the best ways for your child to learn about the world. Now that he can grab things, he's bound to try to use some of your stuff. His fine motor control isn't developed enough to let him do delicate tasks, but he can hold your comb or brush up to his hair and try to drag it through his fuzzy mop.
If he can get his hands on a toothbrush, he'll attempt to give his gums and teeth a once-over too. In fact, he may scour his mouth for hours once he realizes how good the bristles feel on his gums. Be careful: His grand finale may be to throw the toothbrush into the toilet. (Better give him Dad's!)
Wanting a Lovey
10 to 12 months
Not every baby becomes attached to a comfort object, but many do around this time. You may have to lug a stuffed teddy along on every outing.
Grin and, uh, bear it. Your baby is going through some big changes right now, like learning to cruise and take his first steps—away from you. He's bound to feel insecure at times, which is where his stuffed animal (or blankie or cloth diaper) comes in. Its cuddliness reminds him of the affection he gets from you, and it gives him something to hold onto, literally, as he faces up to the new challenges in his life.

You've sent plenty of smooches your baby's way. Now she may blow one back. Just being able to bring her hand to her mouth is a big development. At birth, her arm muscles were contracted and her hands were in fists. By about 8 months, everything had loosened up enough so she could hold a bottle. Now her control's so good that she can put her palm to her lips and flick it away with bravado.
There's more. She's showing that she likes giving affection—a sign of healthy emotional development. Try merely saying "Blow a kiss!" and see whether she does it; if she does, she's also got a great understanding of spoken language.
