Calvin turned 9 months on the 16th. He had his 9 month checkup on the 23rd. He is 19lbs 5.8oz and 29 1/2in now and his head is 17 3/4in. The pedi said that he is average weight and that he is tall. He doesn't have to go back until his 1 year checkup now. Calvin has definitely been picking up on the sign language. He signs milk now and he squeals when I sign milk or eat. He can also stand alone for a couple seconds but he is afraid to do it very long. Can't believe my little guy will be 1 in three months.
