Other children and new baby's birth?

We have 4.5 yo DS and baby girl is due next Thursday via scheduled c-section.  I anticipate I will be in the hospital for possibly 3 days.  MIL will bring DS to school that Th morning to keep DS in routine of going to school.  Then from  there, we just don't know what will be best for our little guy!  We were thinking that MIL would pick him up from school and bring him to the hospital to meet his baby sister that afternoon, and then I was thinking maybe DH could go with MIL and DS to MIL's house to help DS get to sleep (DS has never slept at MILs house before...) and then DH come back to the hospital to stay with me, and then MIL would bring him to school the next day again.  But then we were wondering if it would be better to wait for DS to visit Friday so he doesn't have to see me but he can't stay with me?  DS is staying at my mom's Friday night and he is much more familiar with her and has slept there before, so we think he'll be better able to cope with leaving me at the hospital that night.  But I feel bad if we wait 2 days for DS to visit.  

I just don't know!  

How did you handle it?

Thanks!
