My MIL is great, except she's not the greatest house keeper. Every time my husband brings our 3 month old to her house I tell him to not let her lay him on the floor. He's small enough now that he can be in the swing or pack n play, but I'm worried about once he becomes mobile and he will want to be on the go. I don't know how I tell her I don't want him on her floor when she has other grandchild whose mother doesn't see it as a problem. I'm not there every time the baby is there to keep him off her floors covered in dog hair and food from the other grandkids. I've cleaned the floors myself when she wasn't home, but I think she would be offended if she knew I did this! Help!
