I found that Tyler went through several stages of preferences, some due to teething, some for no apparent reason at all. As long as what he wanted was healthy and didn't need to limited, I went ahead and gave him what he happened to prefer and didn't make an issue out of it. He also went through a stage of preferring purees around that age, and continued to like them off and on until 18 mo or so. The way I see it, who says he can't have purees at a certain age? Your best bet is to ride this out and try not to make a big deal out of it...he'll pick up on your anxiety and that won't help the situation. Hang in there, it's just another phase!
