2 weeks past my due date i had a 3 day old baby and very huge (36J), very tender, newly engorged breasts (that was the day my milk came in). I was able to get out of bed for 40 minutes to help clean up when the dishwasher overflowed and flooded the kitchen, but i was exhausted by that and stayed in bed for the rest of the day. I didn't leave the house until day 8, and i had a completely normal vaginal homebirth with no complications or stitches. In terms of dress size, by day 4 i was back to my pre-pregnancy weight (i only put on 6kg), i have friends who have toddlers and still trying to get the baby weight off, i think it'd be hard to guesstimate what dress size to order.

Inductions are responsible for many horror stories among mums, and though they CAN go entirely to plan and work out fine, they often lead to complications and sometimes to tragedy (there was a woman mentioned here recently whose induction became an emergency c section which became an emergency hysterectomy to save her life). Some inductions are necessary and those can save lives but it is a weighty risk to take for a wedding IMO.

I think your idea sounds a good one - you will be in the role of BM for organisation/support, but on the day you will take the role you can best cope with as either a guest or a strong mention and thanks in the speech, if you're still in bed with the baby (or not yet with the baby). Though i know what you mean about DH being involved in their wedding being important, keep in mind that he would probably much rather miss their wedding than the birth of his child.
