It is always an anxiety provoking thing to learn that they are dropping weight. So hugs...

My first child was breastfed until she was 12 months with food for fun until then. She just wasn't that interested most of the time.

I guess I would investigate other reasons he may be losing a bit of weight but I also wouldn't decrease her milk. I think it's only us "civilised" nations that tocus so much on solids & this can stress us Mamas out!

Just remember that you will get through this stage - keep following your instincts.
