I enquired about these as wanted to meet mums due at the same time, they offered refreshers , which didn't come with a reunion after , and wouldn't let me on the normal ones eve if I taped my mouth up! as I already had one kid.
I must admit wouldn't want my hubby to go with me tho ....
Going to try pregnancy yoga or something simular I think to meet mums, but would recomend any pregnancy classes esp if your first to meet mums and freinds for life
