I'm probably not going to be much help - but I had a poodle years ago who would go in the house if something changed. When I had my daughter, he started going in front of her bedroom door. When my husband's sister came to stay with us for a few weeks, he started going in her room. If your baby checks out healthwise (and it sounds like she has), then has anything else in the household changed that might have upset her?
