It's a scene that has been played out by TV, movies, and print. A set of new parents *finally* get the baby to sleep. They fall into each others arms and as soon as lips touch...
Cue screaming baby, stage left.
As cliche as it feels, almost every new parent has been there.
Could there be an reason our new babies interrupt sexy time?
As a matter of fact, there is a new theory about that.
It could be that your baby is intentionally, although subconsciously, attempting to sabotage your special time. It's not because your baby wants to be the worst wing man ever. They just don't want to share your attention and it's not your partner they're working to keep away, but a future sibling!
That's right! Evolutionary biologist and geneticist and professor in Harvard Department of Organismic and Evolutionary Biology, David Haig has a new theory on why newborns evolved to be so disruptive!
We know that breastfeeding often triggers lactational amenorrhea , or the delayed return of a woman's cycle (and therefore fertility). The more often a baby nurses, the higher chances of a delayed return of a baby's cycle. Haig suggests that this is intentionally to delay a future sibling and therefore increase the odds of survival.
Nightwaking increases in the second half of the first year of life and is increased in babies that are breastfed. While some causes of nightwaking are entirely separate, this hypothesis could explain sudden sleep pattern changes in breastfed infants over six months old.
