I wish i could go back 2yrs and tell myself to stop reading so many labels and give myself a break. I remember being horrified when the HV suggested I give DS fromage frais, rather than the organic natural yogurt I was giving him with organic pureed apples (home done of course).
Saying that I didn't give him chocolate till he discovered it himself this Christmas at the age of nearly 2, and even now he doesn't eat lots and only really likes buttons. My mum gave me such a hard time every time I went there "is he eating chocolate yet" she just wanted to give him some all the time - it's a nanna thing I think. I just used to say no every time, and whilst I know she didn't like it, she wouldn't say anything - and finally said to my sis last week how well behaved he was and not hyper at the end of the day, because I don't let him eat too much rubbish! - Don't get me wrong, he eats plenty of biscuits and cake now, and DD will be getting FF not organic natural yogurt when it's her turn to be weaned, but I'll still be PSB about the chocolate with her too. - Sadly, I think DS will be right behind me offering it to her whenever he has some this time !
So no, YANBU, yes maybe PFB, but we all go through that. If it's important to you, stick to your guns, but maybe ease up and stop reading all the labels - and there is sugar free calpol, but like me 2yrs ago, you'll probably agonise over the sweeteners in it before succumbing eventually!
