antenatal/birthing classes

any FTMs who havent/arent doing antenatal or birthing classes before having their babies? i havent had any and my family are hassling me about it but my husband and I have watched online birthing classes and been reading a lot of pregnancy books etc plus we dont feel like we need the classes, ive been baby sitting my niece and nephew since i was like 12 and my husband did the same with his nieces and nephews, we feel more than ready, we know about all the things that can go wrong and everything that can happen, so my question is for mums/dads who didnt do the classes, after you had your baby did you wish that you did do them or did you feel confident and fine without them? if that makes sense lol. also dont comment if you're just going to attack me about not doing them.
