How do babies grow so fast? Three months have flown by, and we no longer have a little infant in our home, but a big smiling, laughing baby. Everyone still adores him and loves to cuddle with him and they do anything they can to make him smile or laugh! Every baby stage is so fun! I love watching him learn to interact with everything around him. He now goes to bed cheerfully and wakes up happy, and it is one of my favorite things to listen to him coo in bed as he goes to sleep or waits for me to come get him in the morning. He's big enough to sit in the Bumbo now, which is a fun thing when I want to do a little sewing!
