The thing that is very likely actually swaying is maternal condition and overall fertility (which depends on your condition). Being in somewhat better condition (due to good nutrition, muscle mass, enough sleep, etc) tends to sway blue, and being in slightly worse condition tends to sway pink. But the catch is that anyone in actually bad, or even slightly bad condition reduced their fertility so far they cannot get pregnant at all, and it's very easy to drop into bad enough (in other words, you don't need to be feeling run down, tired, weak, or very sick to be in low enough condition to not conceive.) It happens quite frequently and usually you feel perfectly fine when it happens. You would not think you are in bad condition or having reduced fertility, in many if not most cases, you'd feel normal and your cycle would still be normal. This can happen, for example, when you're breastfeeding and just after you had a baby as well, even if you are in overall good health. And additionally breastfeeding and postpartum hormones suppress fertility too, regardless of what kind of condition you're in, because that is nature's method of birth control to ensure you don't have too many babies at the same time.
So what can happen postpartum is that most people can't get pregnant anyway, and these are the people in the "worst" condition with the most suppressed fertility. Anyone who CAN get pregnant in that first year, with a boy or a girl, is by default already in pretty good condition. Many people can't get pregnant at all till 6-12 months or even longer if breastfeeding. So of the group that gets pregnant, yes, close child spacing does sway pink we believe because it equates to lower condition and the hormones of postpartum and lactation gently suppress fertiity, but a whole lot of those people are in really good condition, and their fertility already can't be suppressed much for them to be able to get pregnant.
Long story short this means that even though close child spacing does sway pink, and I urge blue swayers to wait at minimum 12 and more likely 18 months to TTC after having a baby, it does NOT mean that all or most babies are going to be girls who are conceived this close together, because most of the people who are even ABLE to have a baby at all are going to be in the "good condition, very fertile" category or else they wouldn't be getting pregnant to start with!
It's one of those things that sways, but like everything in swaying, is not a guarantee or even easy to see in the general population.
