I haven't read all the posts, but my daughter developed a nut allergy aged 10 over 20 years ago when it was unusual.She was blue lighted to hospital twice.
I would not want nuts banned on flights, nor would she, where do stop, - people banned from eating nuts in public like smoking? Someone could easily have eaten nuts and wiped their hands on a bus seat, train seat, there are risks everywhere.How do you control it?
My daughter has travelled widely to far off places such as the jungle in Peru, Borneo, Sri Lanka etc and lives abroad still and not come across a nut allergy like people seem to have here, they looked at her like she had 2 heads in some places when she said no nuts please!
I am caring for a 9 month old baby at the moment who has a CMP allergy and we are actively giving her nuts in some form such as butters, pastes, crushed in food most days to ensure that she is exposed to allergens.
My daughter was desensitised after 16 years and eats nuts daily now and really enjoys them, she missed them greatly as she had eaten since 2 years old until reacting.
Interesting comment about the nipple cream, I used one for 9 months she was totally breastfed unlike her brother who has no allergies and was bottle fed. She also had eczema ( gone by age 7, so typically atopic) and I was later aware the creams had peanut oil in it, whether that contributed to her developing an allergy or not, I don't think so until there is hard evidence.She still has asthma, but only bad in the UK, so probably pollution induced.
It seems that every child I look after now has an 'allergy' of some form, I no longer cook for all my little people as they all have different diets and bring their food which is hard to manage at times, but gives parents peace of mind. I believe a lot of them are self diagnosed too, intolerances due to early weaning - a baby is sick after eating something so they must be allergic, some of them have such restricted diets it can only be detrimental to their health.
