need advice on hubby situation please

Bi
I am booked in for a scheduled c section this comingThursday, now my problem is my husband doesn't think he will handle it in the theatre with me (he is a butcher) so deals with blood etc daily, but gets sick at the sight of human blood I think it's just crazy but I know he can't help it. 
This is out 3rd child others are age 6 and 8 they will be at school on Thursday which starts at 8:30 now I'm booking in for 7am they have to prepare me etc I suggested to him 
He drops me off and gets the kids ready for school etc does the school drop then comes by the hospital hopefully in time for all the action but if not I'm not fussed. He got a little upset I think he went quite when I questioned it he said he would prefer not to as he will be sick , we have no local family or friends to help with the older 2 so to be honest he doesn't have a choice as the hospital is no place for 2 kids while mum is in surgery.
Any thoughts on what I should do? 
I think he is ok with it and so am I like my god he can't even attend a ultrasound because he gets sick that's how weak he is. And I don't want the Dr's attending to him while I'm laying there open and helpless lol
