Toby at 4 months

Toby is 4 mos old now and he is growing fast. He can roll over on his tummy and jumps while he is in his jumper. His development is doing great. He is very opposite of his older brother Tyler. Tyler didn't roll over until he was 7 mos old. We think that Toby will learn to crawl pretty soon and starts walking earlier than Tyler was. Toby is such as happy boy for the most part.
