My daughter ended up in hospital being tube fed for 5 days because she wouldn't eat or drink anything (and we spent a number of weeks last year being borderline for hospitalisation for the same reason) so on medical advice I offered a huge variety of things including juice, jelly, icecream, lemonade (and she was under a year old) etc.  She wouldn't take them either but some of these comments make me wonder how many parents observed me and judged my actions at the time.  We all judge people - it is human nature - but unless we are with someone all the time we really have no context for the decisions that they make.  In public places you might well see my children have a McD's chip, a muffin, a biscuit or a fluffy...but you don't get to see the fact that my son can name and will eat most of the things grown in my vege garden or that my daughter would eat cherry tomatoes and blueberries all day if you let her.  I believe in healthy eating - but to me that means growing up having experienced a variety of food / drink and understanding where it comes from and what it is made of.  It also means growing an understanding of what foods give you what benefits - rather than what foods are 'bad' or 'good'.

ETA - I must admit I'm not a huge fan of foods like chips being routinely offered at playgroup / music because I think there are loads of other great options that are just as easy and much better nutritionally.  But I'm not opposed to the odd one being offered when they are around.
