Scientist Says Your Baby Doesn’t Want a Brother or Sister


Have you ever suspected your baby of trying to kill your sex life?

That may be exactly what your little bundle of joy is doing, says evolutionary biologist David Haig in the journal, Evolution, Medicine and Public Health.

According to Haig’s theory, when babies scream out for their moms in the night, they don’t just want comfort or to nurse — they are unconsciously plotting to stop them from having sex. The reason? Haig believes babies want to prevent their moms from becoming pregnant again.

That’s right, the Harvard scientist suggests babies want to keep mama all to themselves. In other words, they do not want to compete for their mother's time and attention and are attempting to ensure their own survival.

Sweet or sinister, that is for you to decide, though Haig argues that when babies frequently jolt their moms awake, they are ensuring she’s too tired to feel amorous, thus serving as a built-in birth control method. Biologically speaking, breastfeeding also delays the return of a woman’s period, thus warding off the potential creation of a sibling. 

While Haig’s theory has been debated by other experts who argue babies cry out in the night for all sorts of reasons, among them overheating, feeling cold, hunger or simply craving closeness, it is likely to grab the attention of anyone who has suffered a dip in their bedtime liaisons post-baby. 

Whatever the reason, the next time junior screams for you at 2 a.m., you may be looking at him — and his motives — a little differently. 

What are your thoughts? Do you think babies are trying to destroy the romance?
