So....I'm am such a very happy mother today!!! Tre' for the first time sat up by himself today! We were in the church nursery and I sat him in fromt of this toy. He sat up and played with the toy for about a minute. He was laughing and giggling and when he realized I wasn't holding him he fell back. It was so amazing to see this. It is a blessing to see how strong he is getting and all the developmental milestones he passes !!!
