You can totally go alone! They should not discriminate against the fact that he can't make it.
Ok thank god, if only they made the class on a Sunday he could make it. Hopefully I won't be the only one by myself
I went with my mother in law with my first so I wouldnt have to be alone since the obly time they offered it was while my husband was working. Its totally ok to go on your own too!
Take a voice recorder so that he can get the info he misses. It's a great way for you two to take the class together and a way you can remember things you don't want to forget. :)
