Partners family came round today and we're all over my 4 month old boy, which is lovely to see! However.. his dummy fell on the floor and my MIL picked the dummy up and put it in her mouth to "clean" it! I was horrified, i took the it off her before she put it back in my sons mouth. She was offended by this and said I was being too precious, AIBU? I'm fuming in all honesty
