Our DS wanted to eat, so we introduced solids early. I don't regret it at all, in fact I'm really happy about it. DS is not a picky eater like other toddlers we know - he loves food, especially fruits and veggies. He tried a bite or two of banana around 3.5 mos, but didn't really eat more than a bite of fruit once every few days until he was 5 mos. At 5 mos on the dot he started really demanding to eat, although even then it was only about an ounce at a time, about once a day. It's not like it's an overnight thing, they don't suddenly start in on 3 meals a day. That surprised me a little, how gradual it is when you just follow their cues. To me, listening to what your baby wants and asks for is at the heart of AP, so that's what we did. There's no history of allergies in our family either, so that helped us out. By about a year, he was up to regular meals/snacks.
