When my grandpa died last summer, I decided to leave the kids at home with DH. It isn't really appropriate to bring young children to something like that IMO. It's hard for them to see you crying and they don't understand, and it's difficult to give them the attention they want when you're upset. It was much, MUCH, less stressful than it would have been if I had brought even just one kid. I'm glad I didn't.
Does your mom see your child a lot? If so, I think she probably isn't thinking very clearly, it's not something you want to be chasing your baby around at, you'll want to focus on the funeral and everything than worrying about him. If she wants to see him, tell her she can see him afterwards. That's just what I would do if I were you.
I'm very sorry for your loss, btw. I went through this last June.
