I didn't have that problem, but I remember that mummygoth did. Unfortunately she's not around all that much any more as she doesn't have internet connection at home any more.
I think she found it worrying at first and then just realised that all babies are different and want to eat at different times. Some babies do seem to wean themselves, which can actually be a bit of a blessing.
I think the thread about it is called weaning. It's just been posted on several times again today, so it'll be in the latest threads.
