Well, no harm going. I went for prenatal classes and I must say the info shared can be easily found online or fr friends. Just that I want my hubby to be more invloved as well. That is why I insisted that he attend with me. Usually, the mummies are the one who are more proactive in looking for answers online but not the men. So getting them to attend classes with you will get them involved and excited about the arrival of the baby. Also, they will be nmore appreciative of what mummies went thru and are more informed when the baby is here. I think my hubby learnt how to swaddle a baby from the class and he did a beta job than me!
So, i suggest that you and your hubby attend the classes. It is also a time for bonding for the both of u!
