The average age for women to be diagnosed with ADHD used to be 44 years old. It is declining due to better diagnosis tools.
A criteria for ADHD is hyperactivity. But 25% of children exhibit hyperactivity regardless of whether or not they have ADHD. This led to a lot of misdiagnosis.
ADHD untreated can result in it being harder to treat. The brain falls behind in it's development of the frontal lobe. Early treatment in the form of psychoeducation and sometimes medication, reduces ADHD problems later in life. In some cases to the point of no longer needing the addition of medication.
While it isn't possible to develop ADHD, the enviroment can greatly impact the brain's development throughout childhood and adolesence. Influencing the severity of ADHD.
Doesn't really matter. The moment the people hear it's male or female, determines how people will treat the baby. Put a baby boy in pink and don't tell people, and people will talk to him like they would to a girl.
Whether or not people accept the small chance that the kid turns out transgender, depends on their personal views. I doubt a gebder reveal party is significant. Besides, it's a party for the parents to be. Not the baby.
On the contrary. A shit, blood and piss shower correlates with a better immunity. Babies born via c-section are more prone to infections. That shower of vile is our welcome to the world.
It's genuinely upsetting. The option to be a house wife/husband is becoming rarer. Everyone needs to work to provide enough for the household. House hubbies are lucky men.
Like taking off your shoes before entering someone's home. Why bring street dirt into a living space? Common sense in many asian countries, non-existant sense in the netherlands.
It also lowers male aggression, which protected babies from infanticide. Here come angry papa responding to the baby alarm!
In most primates, males commit the most infanticide. Humans are the exception. Infants are almost never killed by men. Women often kill their own newborn out of severe trauma. Though some kidnap and kill out of jelousy. Never trust a woman having a hard time getting pregnant. Never let her near your pregnant wife. Never let them alone with your newborn or young child.
Killing your own offspring out of spite is a very useful evolutionary advantage in species that need to put a lot of energy in their kids. Male forced you and fertilized your eggs? Just recycle and start over next time. In humans, it means not putting years of energy into a child forced on you. Kill and start over with a stable partner. Because of this, rape is only about seeking dominance and control over someone. It has nothing to do with reproduction anymore. Men commit more sexual assaults than women, but the motivation behind rape is the same. Women may be less violent, but still often torture their victims in other ways.
Adding factor is serial monogamy. Animals who lost their partner, are willing to neglect their offspring to increase their bond with the new mate when he/she doesn't accept their offspring. Humans do this too. The cold stepparent.
Baby killing is a natural behaviour. Albeit a horrid one. It's a way to maintain bodily autonomy for females in general, and especially useful when two parents are more succesful than a single parent. Menstruation made it so that infanticide would be even less likely. Menstruation reduces the chance of pregnancy by 40-60%. It's a preventive misscarriage known as embryonic wasting.
The defensive behaviour of reducing male aggression led to women crying more than men. Baby cries don't lower women's aggression. It might increase it. The smell of babies for sure increases female aggression. Mostly to protect their child from a jelous/grieving female who lost their baby (female-female competition is understudied) or from a controlling male bachelor looking to get the mother to ovulate again sooner so he can mate with her (with or without consent!).
I think it more about detail oriented thinking rather than the big picture.
