my son is turning 1 tomorrow. For the last 4 days he has been using his teeth while nursing. It's not a bite. It's more of a constant scrape, like he's keeping his teeth almost closed the whole time. He's sucking the nipple through his upper and bottom teeth... I've tried pulling away, I've yelped "no" and "ow". I don't know what to do. I plan to ease into more pumping and bottle feeding but I can't switch him over 100% immediately. He's doing this every time. My nipples hurt non-stop and I'm cringing now when he's hungry. He's bitten me a few times before but not often, though he did break skin and made me bleed. This scraping his teeth on my nipples thing is awful. He's been teething and has 7 teeth so far, expecting #8 any day now. Also, for the last 4 days he's been waking up at 1am wanting to nurse and then again around 4am (normally sleeps till 6am).
