Hospital arrangements for my toddler?

So I've been thinking about who I want to be at the hospital when I give birth and I honestly just want my SO there. We have a 4 year old though and I'm not sure if the whole birthing process is appropriate for his age. (Lol) the reason I only want my SO there is because with my first born, it seems like everyone and their cousins were there (not really just both sets of grandparents and our siblings) and wanting to hold my baby and talk to me and all and visit. Not anything wrong with it I know they're just excited! But I was SO tired and just wanted to hold my baby and close my eyes and have dad by our side.
