Cooper is 9 Months Old!

Cooper turned 9 months old Monday. and today he added quite a few tricks. He has been crawling up the step in our living room for a couple months now but when he wanted to come down he would sit at the edge and squeal. Today he has came down the step by himself twice! Also, he does not like to feed himself smalls things like gerber puffs. He opens his mouth like a bird and expects someone to put one in his mouth. This evening he sat in his highchair and ate puffs by himself(with mommy in the chair beside him) for about 15 mins. He is getting so independant!
