Yeah right. Why don't you people feed your own fears and leave others alone.
The recommendations of organisations change all the time, just look at what was said about SIDS ten to twenty years before and what they are talking now. Ridiculous.
What norash meant is that, in the same way kids develop different in terms of sitting, etc, also kids internal organs and organism might develop not all in the same pace.
Your kid might get eczema and neurodermitis from things you might not even consider today and are not in your control.
Anyway, recommendations are just recommendations and are not supposed to replace your own thinking and decision making.
At the end of the day mummy knows best.
BTW: Kids in Africa are weaned from about 2 months and seem to be just fine.
As I said before: Feed your own fears, not ours.
