I had a lot of the same issues when Tyler was younger (and still do!). I followed Super Baby Food as well and I was super paranoid about sugar, especially as he approached 1 yr old. When we'd go to playgroup, everyone would get out their kids' snacks...a bag of Cheetos, a chocolate bar, or cookies. I'd get out Tyler's fruit and wonder if I was being realistic. Seriously, the only food he ate that had ANY sugar in it was Yobaby.
He got his first taste of sweets on his 1st birthday when he got birthday cake, and I seriously couldn't watch him eat it! Since then, we make it a point in our house not to eat junky food in front of him, which has actually resulted in us having less of it around. And if he chooses not to eat the healthy meal that's in front of him, we don't give him something sweet just for the sake of getting him to eat. He goes hungry until he's ready to have a healthy snack later. As he's gotten older, he's gotten more curious and wanted to try new things, and we've let him. He can have a bite of a cookie I'm eating or share an occasional ice cream, but his treats are spread few and far between so he doesn't think to ask for them day to day. If we're at a friend's and they offer him a cupcake, I'll let him have it or we'll share it, but we don't have them at home (not that he knows about, anyway!). We don't make a big deal of it or label any kinds of foods "good" or "bad," he's just figured out that treats aren't an everyday thing.
Now that Tyler's 2.5, I feel good about the way we've chosen to do things. I doubted myself a lot along the way and wondered if we were weird, but I love that he happily fills his tummy with healthy foods and gets more excited about raisins than he does about cookies. So for those of you hoping to minimize sugar...go for it!
