Hospitals' policy about baby's sibling

Za

Hello everyone!! I'm due in Oct 2nd week and I've a 16 months old baby boy who wil be 21 months old when new baby will arrive. He stays with me at home 24/7 and will never go to another person other than his dad and that too for a short duration. As time is getting near ,I'm thinking if hospital will allow us to keep him with us during labour and delivery. We do not have any grand parents ,aunts ,uncles nearby as we're overseas here in US. So he has nowhere to go even if they don't allow . If my husband keeps him home then I'll be alone in the hospital. Anyone with similar scenario?? I'm worried for my lil boy who can't stay away from us .Please tell me what should I expect from hospital regarding toddlers in labour and delivery.
