Thanks everyone! I am thinking you might all be right - it must be a let-down issue. So that's good - it means it will resolve eventually.
I guess I didn't have these troubles with DS1 as we took a long time to get a good bf thing going.
LOL Jennifer - my mother's group aren't much into bf. I can only imagine their horror if i lay down to feed!!! I'm laughing just picturing it!

Thanks again
Jo
