Hi,
I am so sorry that nobody has replied yet, i just saw the post. How old is your DD? A touchy question but, do you get hostile with each other (even bickering ) in front of her? I know children are extremely in tune with parents emotions. Our 2 year old if ever things are different between her Dad and I she acts up a bit, and looks for attention. I don't know about smaller ones. I don't want this to sound like a cliche but, have you went to counselling marriage or alone to see how to deal with things. I do know that babies feel stress, maybe her teeth are moving, that used to cause night changes with my daughter , worse than her teeth coming through. I hope you find a solution.....((hugs))
