So have recently decided to wean 20mo DS off bf, and from a couple of other threads I know there are others in a similar situation, so thought it might be good to support each other.
My reason for stopping bf is because we want to ttc, but my periods have not come back and as I've just turned 39, I don't feel like I've got time to hang about.
DS normally feeds first thing in the morning, about 530 when we get home after nursery pick up and at bedtime (feeds to sleep). On days I'm not working he usually has another feed at some point during the day. He has been night weaned for a few months.
Plan is to cut down initially to just morning and bedtime feeds, then drop the morning feed and finally the bedtime one. the bedtime one is the one I'm most dreading stopping, partly because he's always been fed to sleep at bedtime, and also because it will mean the end of bf 
Today was the first day he didn't get his 5.30 home from nursery feed, which went better than expected. He asked for 'mummy milk', refused milk in a cup, but happily had a satsuma. Then I took him in the garden to play until dinner was ready. I was expecting more of a fuss, but so far so good. Will see how it goes tomorrow.
Anyway, that's probably enough rambling from me, would love to hear from anyone else going through similar.
