I so feel your pain! DD1 was similar at the same age, and it drove me crazy in so many ways!
Im sorry I have no advice for you, I hope for you it passes. Thats at least what it did with DD1. Also Dh had to go away for work so everytime she saw him she got excited and spent all of her time with him and couldnt care for me. So besides that I dont have much for you, except I know how you feel
