I've been breastfeeding for the last 17 months and mentally I'd planned to finish up at around 18 months, or longer if it didn't feel right to stop then. However for the last few weeks my 17mo dd has been asking for more "juice" when she finishes a feed. I only feed her when she wakes in the morning and last thing at night. I've been ignoring the morning request and just giving her breakfast after her feed, but in the evening I've been giving her around 100ml of cow's milk as well as a breast feed. I feel that it's reaching its natural conclusion but I'm not sure how to make the transition and I'm also worried about giving her the right amount of milk as she's been waking in the night lately, every couple of hours, and crying for a few seconds then going back to sleep but she used to sleep solidly.
Can anyone tell me
a) How to make the transition, and
b) how much milk she should have in a day and how to space it out?
Thanks in advance :)
