I stayed in hospital for five days after dd was born. It took that long to be able to walk with the stiches after episiotomy...
honestly, being a bridesmaid will be hell. walking down the ailse looking like a cowboy just off his horse, or slighly hunched to protect those stitches is not a good look.
you will have assymetrical boobs as they supply milk. you could be feeding baby every half hour if they are like dd. they may leak as well, especially when babies cry. or randomly for no reason other than they just do.
you will still be bleeding. probably like a v heavy period at that stage. do you want to be wrestling with a maternity pad the size of a house brick whilst in a posh frock?
sitting down may not be comfortable, bruised, stictched, and wih piles.
oh and you may be light headed from very little sleep.
you will probably need to pee every hhour as your pelvic floor will be protesting.
if you are unlucky you may still has spd and pelvic pain which makes walking uncomfortable/painful.
