Spitting out solids

DD has been self-feeding for about a month now, and will only allow me to feed her yogurt.  I think somehow she understands that she can't make that happen herself yet...  However, now she's putting the food in her mouth, chewing it a bit, and then spitting it out.  Thank God for my four-legged furry portable garbage disposal, she takes care of most of the mess!  I'm sure this is just a phase we're going through, and she's still happy and bf-ing well so I'm not very concerned, I'm just wondering if anyone else is or has experienced this.  Did anyone go back to purees for a spell?  She is just getting over a sore throat, so I thought it was tied to that, but she seems to be feeling much better...  Just looking for some input!  Thanks, ladies!
