Mom wants to come to US appointment

I have an ultra sound today and blood test. My mom realllllly wants to come to the US. I asked my hunny if it's ok and he said it is. What do you all think? Is it between just me and my husband? Or is it ok for mom to be there too? She's just so incredibly excited. We already had one US.. And it was just me and my husband there. Let me know your thoughts.., my husband is so nice, that he would never say no.
