I can't find the AAP info!

I've been searching for a while but I can't find ANYTHING, straight from the AAP, that says delay solids till 6 months. Everyone SAYS that the AAP says that. However, all I can seem to find from the AAP website says 4-6 months. Does anyone have a link to an article on the actual AAP website that says delay to 6 months? I'm not doubting it exists, I just can't find it and it's driving me nuts!! Thanks in advance!

My pedi said 4 months. She is strict with AAP guidelines. No link.....
My son was not ready until 5 months....
