Just noticed recently my youngest daughter have some habits that used to not irritate me but the few days just drives me nuts. She been clingy since I became pregnant n that ok but she would sit beside me n squeeze n rub in my arm. N sit on my lap which is ok but she would squeeze n pinch my chest n rub it hard. I know why she does that bc I breast fed her n she used to do that when she wanted milk but she no longer breast feed n me being extra sensitive n those things irritates me so much. She don't n won't do any one else like that. She like to stick her hand inside my bra too for some reason. She knows my milk dried up months ago.
