I know people are going to call me mean

Or selfish for this but to each their own. What's a good way to keep people from not holding my baby after I deliver (when i'm in recovery) ? With my 1st child my in laws would stay at the hospital for hours and take my baby from me and I hardly had time to carry my baby except for feeding I don't want this to happen again I mean they can hold him once but I don't want them thinking they can just hold my baby for hours, I don't want to be mean about it but this time I have to do things differently in order for them to not cross boundaries with me again. The only thing I can think of is putting him inside my shirt so that way they can't just rip him out of my arms
