I am actually speechless at what appears to be your sheer lack of engagement with the realities as described by so many mums here.
the reason I said your mum might need to support you after the birth is that you are likely to be exhausted, sleep-deprived, sore, starving with hunger if you are BF and have a hungry baby, getting no more than 2 hours sleep at once, and sore from stitches- and you may feel very weak if for example you lose a lot of blood.
I'm sorry if that sounds harsh but after pages of posts you don't appear to have cottoned on to anything anyone has said.
Your baby is not a doll who will lie 'in the front row' of the venue and sleep to order. They are likely to poo, scream, be sick and maybe all 3 at once during what is supposed to be a solemn exchange of lifelong vows.
On the other hand some tiny babies are so sleepy after the birth that all they do is sleep and feed for a few days.
Have you had much experience of newborns through friends or family? Have you thought about the reality of an episiotomy, stitches and all the other stuff that some women have?
