Can the stress of being born cause infants to get strokes or clots?

No: Infants who have thrombotic strokes at birth have some sort of coagulation defect, this is not a normal birth event.

No: A stroke/blood clot in the newborn period is exceedingly rare. If the new baby has a bleeding disorder (generally inherited and uncommon), if the delivery was exceptionally traumatic, or if newborn acquired a serious infection during birth, these would put baby at slightly increased risk. In general, however, the stress of being born is practically never responsible for a stroke or clot.

Yes: About 1 in 4, 000 babies born will have a stroke around the time of birth, often related to the increased tendency towards clotting in the few days before and after birth in both mother and baby. While it's not exactly accurate to say "stress" causes stroke in newborns, birth trauma can be one of many possible causes. Heart or blood disorders, placental disorders, and infection are other causes.

No: It may be "possible" to get a stroke just from the stress of birth, but it seems very unlikely. Babies born by vaginal delivery have their heads and bodies squeezed on the way out (it's a tight fit). Skull bones move to let the head change shape and come out of the mom. Amazingly, babies' brains don't seem to have trauma from delivery. Premature babies, however, can get bleeding after stress.
