Resentment

Since Sienna has been born Sanora is very loving towards Sienna but it is me that she's resentful towards. We had a bit of an insedent in superstore yesterday and if that wasn't a message that something was up I don't know what is. I have been hard on her so that might be it aswell. Her attitude has gone up like 10 notches and I'm not so convinsed that it will iron itself out on it's own. Any suggestions?
