I'm really not a negative person

I have such food issues.

I've only recently begun to figure out how this has happened. I've noticed how my mom treats my son. (I know, blame it on your parents, blah, blah) Every time he gets upset or is feeling bored she asks him if he wants something to eat. She does her husband the same way...actually all of the family. When it comes to my kid I have to tell her repeatedly that he has eaten or is about to eat a meal. He doesn't need anything. Or, if he's hungry he can have grapes/fruit/something healthy/you get the idea. Constantly, I'm having to do this. And she'll still slip him a cookie in the kitchen when she thinks I'm not looking. She really sees nothing wrong with it. Either that, or it's just habit.

Then, I'm over at my Grandma's house, and it's the same way. "Ooohh, he hurt himself, want some ice cream honey?" Well now what kid is gonna turn down ice cream? And what kid isn't gonna pick up on this habit very quickly? He's only two, but he's already on to them. I'm sure. We don't even keep ice cream in the house. We've managed to rid the house of junk and keep it all healthy since he started eating "big boy food."

I went and picked him up the other night after he'd been at Mom's only for a few hours. She goes, "he's been eating nonstop." Ok, I fed him before he came over. He's not hungry. Is there no time that can pass without food?

So, I'm thinking back on my history. Basically, every diet I've ever been on goes straight out the window if I get sick, hurt, go through something difficult, etc. And if I'm not on a diet at the time I just "treat" myself with something even more rich or fatty as if it's because I "deserve it."

Now, I've been around for a while-why am I just seeing this for the first time? And, AND what am I gonna do about my family?
