AFM I loved breastfeeding but I had a LOT of support, DH would cook dinner while I did the last feed of the day, my parents came around nearly every day when I was establishing feeding to hang out washing, bring me food etc. Even then I remember many times sitting in bed feeding in the middle of the night feeling just absolutely overwhelmed by the relentlessness of it, every four hours for umpteen weeks I need to do this and nobody can do it for me. It's hard. I can completely understand the desire to mix feed and the feeling that it is a chore. Most of the time it is a chore - even if you love it it's not like you spend the whole 30-45 minutes gazing lovingly at your kid. 90% of the time it's something that needs to be done and only you can do it.
It takes a massive toll on your body, I got so skinny towards the end because DS was literally sucking all of the nutrients from my body.
Anyway I'm soliloquising but not actually answering your questions. Yes I remember the last breastfeed but didn't realise it would be the last one. When I realised I was upset because it was earlier than I hoped (at 14 months) and I hadn't intended to go cold turkey, but "don't offer, don't refuse". He never bloody asked for the b00b again! He was so delighted with his bottle of cow's milk I felt very rejected!
I look back at our bfing journey with happiness and I stare at mummies breastfeeding babies just a little bit too long because they look so beautiful.
