Recovery time for vaginal birth

How long does recovery take for a vaginal birth?

Ftm and my due date is 6/4 and I'm supposed to start babysitting for the summer on 6/16. Several of my friends have told me I should take all of July off and then only do a couple times a week in August so I can heal. I committed to 4 times a week for the whole summer. People have more than one kid! The girls are 7 and 8 so it's not like I'll be dealing with three newborns! The only thing I'm nervous about is keeping them occupied all day because they're not allowed to watch tv!
