Oh dear, I can see your point, my inlaws bug me too even though I love them, you need to be firm , from my experience if you don't nip it in the bud now it will get worse, they don't understand what your babys routine is so yeh that's frustrating for you, my mil is thick when it comes to her dog, she lets its go right up to my babys face, the dog is lovely and it's fine for them to play but the woman needs her head banging against the wall! Chin up! Xx
