For those who are asking for schemes to be paid not to smoke, good news, in some areas the NHS will pay you to give up smoking, plus you save the fag money.
I don't agree with being given money for a dairy free life, but I don't think it would break NHS bank to give prescription on request to bf mother of dairy free child for sufficient calcium + vit D tablets. You need loads of calcium when bf for your bones and the child's teeth and bones.
FWIW all three of mine couldn't have milk to varying degrees, the girls still don't have much, but ds who was the worst (I had to be dairy and soya free from 2 weeks); also intollerant to potato, rice, flour etc. I had to be absolutely free of even traces otherwise his hernia came out and he bled internally. He is now just 3, eats whatever he likes, gets through 3-4 cows milk drinks a day, and is fine. I know I have been v lucky with him, plus going for zero contaminents initiallly helped. Still feel a bit sad that e.g. Dd2 won't eat ice cream - she possibly could but says they don't taste nice (dietician said not unusual) (btw swedish glace is soya so not suitable for most CMPI), but we find some lovely sorbets instead.
I know it won't help everyone, Couthy's son sounds far worse than ds, but many of them do grow out of it, and being hypervigilent now really does help in the long run.
