So tonight we tried to feed him real rice cereal for the first time and he dug on it.  Still spits his tongue forward a bit, but he was genuinely happy to be tasting something new.  Just mixed it thin with breastmilk.  He has had this a few times before mixed very thin in a bottle, but this time we served with a spoon!  Earlier today he also got a taste of butternut squash and was giddy over that.  Zoe and I were making pumpkin bread for her class and I was mashing up the squash in the blender.  Gave Mr. Avi some on my finger and he leaned in for two more tastes!
