Why Is Jack Jack Laughing?

This morning I got up early and placed Jack Jack on his high chair. Later on, when hubby got out of bed and went to the kitchen we were hearing Jack Jack laughing. He wasn't with anyone. It's kind of creepy so we were wondering what he was doing.

Hubby: Bakit tumatawa yun?!

Me: Hayaan mo na kaysa naman umiiyak.

LOL...
