Teeth aren't an issue, although she has nipped me once or twice -- prompting a stern 'no!' She even falls asleep gnawing on the nipple and that doesn't hurt. Mind you,
Having moved beyond a year, and BLW going very well, it's not about nutrition so much, more about relationship and comfort. And I love that. I have had wobbles, I have fended off criticism and have fed recently in public (I don't really care that much but it can feel a bit like people who notice are quite shocked).
I do sometimes find the acrobatics, the pulling, the kneading and the rolling the other nipple annoying. And I think this closeness (we sleep in the same bed) has come at some cost to our sex life. But we're prepared to put up with that for now.
I don't have any feelings about my body not being my own -- it IS my own regardless, but I do sometimes have a hard time feeling touch overload and feeling resentful I'm the only one who can put her to sleep.
I've also not had a period in 19 months, and while that's in some ways a good thing, I have a condition called Ashermans (endomitrial condition) and need to know I can still have periods because repeat treatment will take ages and I'm 38 and time ticking if I want another child (70 pct sure I do). So while I don't want my body back, I do want my fertility back.
I am not particularly hippyish or earth mothery (although I not have a pram and hoik her about everywhere) but would breastfeed another child to the 2-year mark and more (if it was my last and less intensively feeding) even if there were no health benefits to it at all.
I aim to wind down the feeding (I've cut day feeds out now) to just night time and then to night wean and then to wind down completely by around 2 years. I'm ready and even if she might want to carry on, that's my intention and I'm doing it as gently as I can.
