I have mixed feelings about it, and always have had (well, being honest, in the early days, I was so overwhelmed by the amount of time DS fed for, what I mainly felt was deep frustration and resentment, and then guilt when everyone kept telling me what a loving bond it was supposed to be creating!...)
Now he's older and it's less overwhelming - I love the feeling that I'm giving him something JUST for him, from me, that is exactly what he needs. I like thinking about antibodies in my milk, weird as it sounds, like there's something almost magical or superpower-like in doing it.
I love that I can comfort him so easily, that it's a way of reconnecting with him when I've been physically away from him - it seems to 'reset' us both -
I still find it constraining, in that BOY does he pick inconvenient times and places to decide he's hungry and wants feeding - and sometimes when I'm tired and feeling 'overstretched', I feel it's just another demand on me when I'd like to be on my own -
Dunno. Mixed bag. I know I don't feel the overwhelming and unqualified love of BF-ing that some women do, but it doesn't bother me now.
I have thought back to the first few weeks, and how much BF-ing TIED me to DS, physically, and wondered if the fact I couldn't leave him, and he had to be with me almost constantly sort of forced me to bond with him. It's overwhelming, having a little life suddenly attached to you, and I think if I wasn't BF-ing, I would have left him for short times with other people and run away a bit. Just a day away, that sort of thing.
Sometimes I think being able to do that might have eased my way into being a mother and made it a more gradual adjustment. Mostly now, I think that if I'd been able to do that, I would have taken too much time away from him, and not feel as bonded. Who knows.
Tell you what though - bloody well done for BF-ing twins to 4 months. My head spins just thinking about it.
