My son is sitting up. I was not expecting my 5 month old to sit already :'(. This is 3 months before Jewell. At times I feel like I have a 1st child all over again! I have a strange feeling that my two kids are going to be a bit competitive as they grow up. We keep joking that Jefferson is going to race Jewell in a foot race by the time he is 1. We'll see! Congrats Jefferson on your accomplishment of sitting. You are just too adorable!
