Delia turned 4 months old yesterday. In the past month she has become more alert and interested in her surroundings and enjoys sucking/chewing on toys and fingers. She likes to look at and touch toys and is still figuring out how to grab them. Also, in the past week she's started rolling onto her belly. It was so funny watching her teeter on her side as she tried to make it all the way over, but she does it effortlessly now!
