Thank you so much for your responses. I'm really sorry that I have been offline for nearly a week and not got back to you sooner, but I do appreciate your thoughts.
I find it ever so interesting that although many mums on AIBU said they wouldn't use me as a childminder (mostly because of calcium/'restrictive diet'/emergency procedures etc.), nobody really questioned the wisdom of excluding my DS's allergens from our home. You 'allergy mums' have given me a completely different perspective!
freefrommum, I agree completely that we can't keep our children in a 'freefrom' environment forever. We have to give them the skills to cope with managing risk in the real world
You're right about the dangers of creating a 'falsely secure environment' and I do think it's true that nut-free schools make both children and staff less vigilant than they should be. My situation is slightly different from yours because I am thinking about home educating DS (I have always loved the idea of home education within a peer group of other home educated children, so this is not just because of his allergies, but I do confess that his allergies are definitely a contributing factor).
DS (aged 3) is very, very aware of the dangers when we are out and about (e.g. steps carefully past discarded ice-cream wrappers/chocolate stains on the pavement; always asks me or DH about the ingredients of any food he is offered; carefully sorts play food into piles of things he can eat and can't eat). I am amazed by the maturity he shows at only just 3 years old, and am humbled by how calm he is about the whole thing. My feeling is that when DS is older and has a house/flat of his own, he will probably exclude all of his allergens from his home so that he can enjoy some peace of mind. I want to give him the 'freedom of his own home' while he is still a child... but I do recognise that we all manage these things differently!!!
Eskimomama, thank you so much for your posts, especially the second one
It's true that so many people (including childminders and nursery staff) have no idea about the range of foods that contain dairy! I'm a bit taken aback by the childminder who said she couldn't always be monitoring what children put in their mouths
Most of us deal with this issue by making the environment safe (e.g. putting marbles and other small pieces out of reach) but we do still watch the children!!!
Chocamum - bless you!! - you mentioned "the number of people that worry about a varied diet, do they think all our children are deficient in nutrients?!" Oh yes, I do agree!!! Those of us with allergic children have all got pretty good at balancing their diets! I get so incredibly fed up with all the lovely, well-meaning health professionals, family and friends who think it is impossible for a toddler to get enough calcium without dairy (but I have learned to smile and nod at them all while quietly feeding my son broccoli and spinach instead
)
Anyway, I have decided to forge ahead with my childminding plans. Most of the parents I have met so far are completely happy to go along with my food restrictions. I'm fairly confident that I will get enough business to keep me afloat [crossed fingers emotion!] - thank you again to those who have wished me luck
