I found my DH got more from the antenatal classes than me, cause i had a BellyBelly education.

I could tell him stuff, or give him things to read, but he didn't really take it in until the classes. I guess it depends on how your DH learns - if he'll go through the Pink Kit with you, I wouldn't worry about him missing classes, but if he is more of a classroom learner and needs to have questions answered as he thinks of them, I'd go to the long class.

Hope my waffle helps in some way.
