What to do if you have thoughts which shock you while you're caring for your baby
The biological re-wiring of your brain after you've had a baby can act as a loudspeaker, amplifying the human brain's already existing tendency towards repetitive unhelpful or negative thinking. Unhelpful thoughts often then trigger waves of distressed emotions.
In the perinatal period, your thoughts might become so unhelpful or negative that you experience them as intrusive, and you might even have thoughts which you find utterly shocking. If this is your experience, it's important to know that
-
It seems all women experience intrusive thoughts of their baby being harmed at some stage (most often in the first weeks after the birth), and that half of us have very disturbing thoughts about harming our baby. This is a common thing that happens in our brains in the postpartum period.
-
It's normal to worry that you must be a very bad mother because you have these thoughts. This not true.
-
It's normal to worry terribly that you must be at risk of acting out these thoughts. This is not true.
-
The disturbing thoughts pass in time, as the postpartum period with its chronic stress, hardwired hypervigilance, and complex neurohormonal changes passes.
-
It's best not to try to get rid of the thoughts, but to anchor yourself in the present moment, over and over, practicing a great and tender compassion towards yourself. How difficult it all is! What a relief it is to know that this too, even these shocking, horrible thoughts, will pass!
