Born, anything we can help with re helping you try veganism again? Like Lexi said, there are more alternatives now, if that was your downfall before, and Vegusto is indeed superb. Mmm, that cheese sauce. Divine.
Lexi, DS (2.5) is not in nursery, we have planned to homeschool (not because of the veganism!) him since he was born so worrying about nursery or school is not a consideration for us. I think you have to find a nursery you trust to stick with his dietary choices, or lie and tell them he is allergic.
Re friends/parents, I've rarely had any issues, only one I can think of, when the nanny of a friend offered my son some biscuits with milk powder in, despite knowing he didn't eat milk products, and when I said no thanks, she said 'what, so strict!? How extreme!', but really, in two and a half years, that's the only comment I've had. Everyone else has been really accommodating. Of course, he does get offered random things by strangers (why do people do this!!!!! A real bugbear of mine. So many children have dietary restrictions.) but a simple no thanks has always been taken well (it's usually them offering him sweets and chocolate, they just think I don't want him eating sweet stuff, I guess!). I used to take a small packet of sweets out with me in case he got upset when he was offered something and I'd said no, but he never has.
We did BLW, it really was super easy, he just ate what we ate, no extra cooking, and a happy eater, adventurous boy. No choking or scary incidents either.
