So my son has developed a sense of humor. It's really cool seeing that there are things that consistently make him laugh. Mainly that thing is cats. Cats are just innately funny in his book and watching them do the most basic things will cause him to giggle. Moreover if we make cat noises he laughs. He loves it when we start singing him a son he knows and then stop midway to meow. He also gets a kick out of transgressive behavior, such as my husband gumming at his toys like he does or me lying on my belly. These are apparently things that babies do, not parents!
