Ever since we announced we were going to have a second and it came out it was going to be a boy, I was relentlessly told that "boys are fussier than girls" when they are a baby. I wasn't inclined to believe such nonsense. It was all anecdotal evidence seasoned with the classic "everyone knows that..." argumentum ad populum.
Our boy was born and he is definitely more fussy than our daughter was. At the same time, he is also less colicky than she was. They were/are both healthy babies, growing normally, getting fed, clothed, and changed but it seems like, while she was able to be alone by herself for periods of time while we finished up the dishes or hung the laundry, he cannot stand being putting down.
Keeping in mind that fussy, in this instance, is clearly defined as "fastidious about one's needs" and "hard to please" do studies exist that investigate the idea that boys tend to require more attention from a parent while girls require less? If they do, what was the conclusion of that study?
