5 mins is more then enough at 10/11 mnths DS was usually feeding for 2 mins max, most of the time he wouldn't take the other side. BUT I did notice it does change and he would go through periods of taking both sides again.

When I have re-read this thread it reminded me when DS was about this age that I thought he was weaning as well cause he had cut down on some feeds and didn't seem interested but we are still going and nearly at 24 mnths

I do find that DS tends to not feed as much when he is teething, when I am O and when AF is around so if all of that is having at once I tend to have a slight panic that this is going to be it but we keep going

Goodluck and I hope, if you are happy to keep going, that this isn't the end.
