What do you all do to keep your lo"s entertained and stimulated during the day? I am home alone with ds most of the time and too often I just can't think of anything creative to do with her at this age. We "talk" to each other alot and I will sometimes take her for a walk around the house looking at and pointing out things. Occassionally, we watch Baby First TV together if they have a sing-along segment on. Sometimes I will lay her on her mat and and she stare/bat at the hanging toys, etc.
Can't think of anything else to do with her, and sometimes I wonder if she will nap better if I am better able to tire her out.

Any ideas of things I can do daily with a 21 week (nearly 5 months) old?
