Main board alert

Yes, I've read that in a couple of places. Bottom quartile in a year age-wise is much more likely to be on SEN register in general (including ADHD) than top quartile. I'll try to dig up a reference.

My two have birthdays in July and August, just thought it was interesting.

Still looking for a reference for English schools, but this is one like the ones I've seen before, but for a Canadian school where the cut off day for a new academic year is different.

There is another guilt inducing study floating around in the "news" trying to associate formula feeding with ADHD . Gee, thanks.

I've read that recently too - my ADD brother is an April baby though.

My DS3 (hyperactive 'with a high probability of ADHD) is a January baby.

And I bf till a year. So neither ff nor july/august birthdays are reasons why a DC might have ADHD...

So stop feeling guilty!!

My DS2 and DD2 both have ADHD. He is September born (and BF for 15 mo) and she was March born and BF for 4 years. Scotches both theories.

Dd1 may birthday but she was 7 wks prem has dx of ADHD. She was ff. dd2 last week of August baby bf looking likely an ADHD dx may be in the cards. In the genes more than the birth month I'd say

The ADHD/FF study has done nothing to establish whether the relationship they see is causative or merely correlation. ADHD is highly heritable so an observations of higher levels of ADHD in FF babies are meaningless without data on the proportion of mothers with ADHD who FF or BF compared with mothers without ADHD.

DS1 was mostly BF and born in December (awkward little so and so was due mid-November!)

I don't think any of the things I read was suggesting that there was no ADHD in the older kids in the class, just that it was statistically more likely for the younger kids to be diagnosed with it. Possibly some borderline cases stuck out more because they didn't have the extra maturity to compensate?

Hadn't heard of the BF/FF thing, but in any case mine were both BF until over a year old. Only one has ADHD, but both have AS (we think very strongly genetic).

There are more summer borns on the SEN register. A school can put you on the SEN register for anything they like.

That's totally different to saying there are more summer born kids with a dx of ADHD - which I think is highly unlikely given ADHD dxs are not easy to get.

I'd expect there to be a correlation between kids with ADHD and FF because I'd expect more kids with ADHD to have dyspraxia symptoms which made it hard for them to BF.

Ie I'd expect more kids with ADHD to find breast feeding hard than the general population. Failing to latch on can be the first symptom of dyspraxia.
