Lots of people here talk about feeding their dcs crap food as a badge of honour - it's a weird kind of street cred.
"My kinds eat junk food - so shoot me, ha ha"
[subtext: I am a laid-back cool person and people who fuss about junk food are so up their own bums it's unbelievable]
But.... there's a big worry out there about obesity, about additives in food, about the way bad eating habits often have their beginnings in childhood...... and the concerns are likely to get stronger with time.
Don't you ever worry that 20 years from now when times have moved on, one of your dcs will read your light hearted comments and actually feel a bit that you seemed so proud of feeding them crap?
Whereas what I'd hope for with mine is to be able to say, "Well, you did sometimes eat rubbish at parties and I wasn't all that happy about it, but I let you because I didn't want you to feel left out. I didn't stress about it too much because I knew you ate well the rest of the time."
[subtext: I was never a perfect parent but I did my best to find the balance between feeding you well and not being obsessional about food].
