Who will be with you?

What's your take on having someone besides s/o being in delivery with you?

My mom is my best best best friend and I am having a hard time imagining going through it all without her, but my fiance wants it to be just us two. His reasoning is that his mom can't be there (she passed away 2 years ago this month) and I totally understand that but his mom got 3 grandchildren and this is my moms first. His mother would totally be with us in that room if she was here, no question about it. I just kind of feel like he is taking away this moment from myself and my mom. He has no problem with my mom, he loves her but I think he is just having a hard time thinking about his mom not being there too.
