Today Justin is now 4 months and almost 1 week old and for first time he turned over from on his back to on his tummy on his own — yay! He started sucking his thumb about a week ago too. Most of the time though, he still sucks all of his fingers instead. He's also pretty steady standing with someone or something supporting him a bit and his legs are noticably chubbier and longer. Oh, he started holding on to his feet as well.
