We made a discovery: baby-boy loves Bob Marley. We'd read online that babies like the sound of reggae and similar music that has a consistent beat mixed with laid-back vocals. So I wasn't surprised that baby-boy appreciated 50 Cent, played from my laptop's iTunes. This spurred me to dig up my (very old) CD case holder and look for my Bob Marley album. I don't think I've listened to any of the CDs in this case for at least 10 years. But habit made me keep them, since they don't take up much space.
And baby-boy is all over it. I sing and dance with him through the first two songs, while my back, wrists and voice still hold out. When I get tired, I sit down with him and jiggle him to the beat. By the fourth song in the album, he's dozing off - the perfect opportunity to lay him in his crib.
Of course, the crib is totally useless when he gets the hiccups, which is often. Like now. Coming, baby-boy!
