I'd keep a harness on her and have the leash handy to snap on when the doorbell rings. Buster does the bouncing around, jumping up on people thing, too. He just wants attention but I have him sit before he gets petted. I don't know how Frenchies are with babies, but if they are like their EB cousins they are wonderful. All of my grandkids have had many positive experiences with EBs. The dogs seemed to know they were babies and were very gentle.
