This week Harvard University published a paper on a subject in which I have an honorary doctorate.
If you thought a new baby crying throughout the night was just a painful inconvenience, it turns out the devious little devils are intentionally delaying parents from the thought/actions of additional siblings. In a twisted-Darwinesque approach, babies are naturally/forcefully focusing the parent’s attentions on themselves, until they’re at a stage that they feel secure and strong.
Both of my children were night howlers until the age of three. Needless to say there are four years between them.
Thinking about it, it makes perfect sense, but blaming evolution doesn’t make the unrelenting, sleep-deprived nights any easier to deal with.
