Because I seem to be bad at dealing with it!
Just spent the morning at a friend's house, she's someone I met at a baby group, really nice but we're not really close friends. While we were there she offered my DS (aged 2) a packet of crisps and a fruit shoot. Her DS was having some as well and I don't mind DS having things like that every so often so we said thanks very much. Then her DS started asking for another fruit shoot so she gave another one each to both our DSs. Then once they'd finished that her DS took another two out of the cupboard himself and gave one to my DS. I said no to DS and said he could have water if he was still thirsty but my friend said don't be silly let him have it. Her DS then asked for some chocolate so they both had that as well.
Because we're not really close friends I feel a bit rude turning things down when her DS is having them and she's kind enough to offer treats to DS, it feels as though I'm judging her a bit, as though my DS is all wholesome and she gives hers junk! Which isn't the case at all.
My DS has a healthy diet but I'm happy to give him treats every now and then but now he has had all that he wouldn't eat his lunch and he would normally be napping now but instead he is in his room yelling and throwing things about! So he's going to be a nightmare for the rest of the day because he'll be overtired and I have to get him and DD bathed and to bed on my own because DP is at work.
I know its quite a trivial thing - I should have just said I'd rather DS didn't have three fruit shoots, a packet of crisps and two chocolate easter eggs as it tends to send him a bit loopy, but I'm just too timid and scared of offending!
