How does you SO interact with your bun in the oven?

While it seems that my husband is starting to wrap his mind around the fact that we're having a baby, I have a feeling he really doesn't "get it" yet.  He does ask to look at Glow each morning to see what the baby looks like, but that's about it!  I've also bought him a parenting prep book for dads, which he hasn't yet cracked open.  What about you ladies?  How are your boys handling the prospect of becoming daddies, and what do you do to get them involved?
