Here's what my email said about babies Jack's age:

Jackson Edward is eager for some more sophisticated ways of socializing these days. He loves to play peek-a-boo and trying to find an object that you've hidden under a blanket. A potentially messy, but ultimately fun and interesting, activity for Jackson Edward is playing with cooked spaghetti. The slippery, sticky, mushy consistency may provide oodles of noodle fun!

Encourage Jackson Edward's language skills by speaking slowly and clearly and imitating what he is trying to say. When he says "ba ba ba," say it back to him in a different tone of voice. Listen as he tries to imitate your inflection. He will probably start "talking" when everyone else in the room is talking - a sign he is getting the idea of conversation.

If Jackson Edward has been looking at the same toys or crib mobile for several months, now is a good time to change the scenery. Choose items with bright colors and big shapes, or one that makes noise. And now that Jackson Edward is starting to pull himself into a sitting position, be sure to remove any low-hanging mobiles or wall hangings that he may be able to reach.
