I'm currently tandem nursing my DS2months & my DD27months. I'm struggling nursing my DD daily. She screams "boobie" over and over. Yanks at my shirt, hits, kicks, bites. She's wonderful with her brother and other siblings. She just started this behavior 2wks ago. Last night she woke me 10x to nurse. I'm exhausted & feel like a terrible mother, because the thought of nursing her makes my skin crawl. I love her so much!! But physically I feel violated!!
