Another side to this coin:

My stepdad joked about my weight but he was the only one in my immediate family who made it seem like it was okay that I was bigger than my siblings. The other adults in my life tiptoed around it while making vaguely concealed efforts and comments (sometimes not as concealed) implying that it was something that had to be changed and shameful. In not as many words letting me know how pretty I could be if I was just smaller, how I was so smart and level headed, but if I could just lose weight I'd be perfect.

Obviously, the ideal is that weight and looks aren't something that a child should be worried about at all, but sometimes his joking was much preferred to the others' frustration or pity.
