Re: I'm LOSING it!
Tell your husband to relax and find something else to choose as his favorite time with baby. Like bath time or post-nursing cuddles or middle of the night walking the halls. You need this time to focus on getting nursing right and regulating your supply to meet your baby's demands and the absolute best way to do that is to nurse whenever baby wants to.
Your job right now, your only job, is to nurse your baby. Your husband's job right now should be helping you nurse the baby. He needs to get on board and stop getting in your way. Tell him how important it is to you that breastfeeding works. Ask him for help making it work. Include him in your breastfeeding success and maybe he'll feel more like a part of it. Get him to help you set up a spot where you can just sit and chill with your baby, ask him to help by bringing you water and snacks and taking the baby for a while so you can use the bathroom or take an occasional shower. In a few more weeks when your supply is better regulated and you feel a little more settled then you can start pumping and giving a bottle again, but for now I think you need to focus on nursing your baby and keeping baby happy. Your husband's a grown up (or should be acting like one ), he can wait.
