Little Hank is about 7 weeks old and is giving us reactionary smiles quite a bit now. Especially at 4am when they are needed the most. The really cute part is that we've caught him laughing some! I'll hear a funny little noise and look down at the bouncy seat to find him smiling. Then he will belly laugh again and smile again. Priceless! It will be very hard to catch on video though. The whole thing usually lasts about 15 seconds.
I hope this is an indicator that he will have a positive outlook on life in general.
