I gotta feeling - first real laugh for Jackson

about 2 weeks ago, we heard Jackson's first out-loud laugh. It was hysterical. He thought that Michael and I singing the Black Eyed Peas' hit song "I Gotta Feeling" was sooo funny. He laughed out loud and couldn't get enough of himself. Have tried it again but no luck. We had him laughing to our imitations of Donald Duck recently but there is no consistency. Both Michael and I are trying to find out what makes Connor laugh as it will probably be unforgettable just like Jackson's first time. Hopefully, that blog post will be sooner than later.
