Jacob turned 4 months this week and we have been seeing so many changes in him. First of all he is growing like crazy, he is already 15 lbs!!! He is also getting to be a lot more fun to interact with. He is laughing a lot more, he turns to you when you call his name a few times, he is talking more, just overall a happier baby. He is also able to entertain himself more. He loves to reach for things and try to grab them and loves to play with his hands and feet. We are just having so much fun watching him learn new things all the time.
