I've just been reading about early life influences on adult disease risk - for example, the way birth weight and early growth affect someone's risk of having heart disease decades later.
The experts in this field all seem to agree on one thing: that early nutrition and growth have a significant impact on health in later life. However, because this sort of thing is so hard to study, no-one really knows how it all works, what's good, what's bad, who's the most at risk.
Very frustrating for someone like me who isn't involved in the research but just wants to know what to do with my own children to give them the best start in life.
That's why I enjoy discussing this sort of thing on MN, trying to sort out the clear evidence from the myths. But we can't use our own young children as examples.
I weaned my 2 at a particular age (doesn't matter what). They're now 3 and nearly 2 and very healthy.
So can I congratulate myself because the weaning age I chose was obviously the right one? Absolutely not. I could have got it hideously wrong, and only the next 60 years or so will tell.
We have to take the long view on this sort of thing.
Rant over!
