Is this possible 4 days after being released?

Rhenna

My son's first day of Kindergarten is 4 days after I will have been released from the hospital for my c/s.  My Dr. looked at me like I was crazy when I asked him if he thought I would be well enough to make it.  All he really said though was that I'm not driving to it.  My last c/s was over 5 years ago and the first couple of weeks is a blur.  Do you guys think 4 days out of the hospital will be enough for me to get out of the house and be there the morning of his first day at school?  I really do not want to miss it and will be really sad if I do. 

And if anyone has kids already in school...how long did the first day take that morning?  Is it just showing up and taking them to their class/dropping them off, hugging and leaving?  I'm trying to figure out how much time I will be on my feet and moving around.
