Singing

I just realized the other day that I don't sing much anymore. I started singing to Jacob once he was born and it seemed like I didn't stop singing to each of the kids up until about 6 months ago. I use to sing to the kids while they went to sleep at nap time or when I rocked them. Now we read books but no songs. Geez first thing I use to do all the time with my kids but don't now.
