Passing Time Activities

Any suggestions on activities to do to pass the time with baby. On the weekends, we spend all day together and I run out of ideas or things to do with a 7th month old.

I let her crawl in an open space, play with all of her chewing and sound/lights toys, go for walks, naps, eat solids, even run errands. I still find that there are several hours left in the day where I need to entertain her. She does have some alone time playing independently here and there, but not for long.

Babies need our attention 24/7.. running out of ideas.

Thanks
