Interested in frilly things - there's an image to conjour with this chilly evening. Men - cars

and women - frilly things

. Really, Nanna?
There do seem to be sex-based divisions in interests, likes & dislikes, inclinations. Everything I've ever read on the subject tells me males as a class are more risk-taking than females as a class. Nanna, this does not mean that women whose idea of a fun day is hurling themselves off cliffs or scuba diving are men. No. They are women who enjoy perilous activities.
imprinting, the newborn child is treated differently according to sex, its subconscious social conditioning by the parents.
the female child is encouraged to be safe and cared for more closely, hugged more, hand holding etc, treated more gently.
the male child is treated more hands off and encouraged to take risks more and be more independent.
this also carries on into clothing and toys, how many babies have blue for boys and pink for girls, what first toys are bought for the child.
I will use my child as an example here I had no idea what sex he was before birth we had plain white and yellow clothing and bedding, he was bought cuddly toys.
as he got older he developed an interest in toy cars, this maybe because I bought him a set of magnetic cars as a baby, he also maintained his love of soft toys, as he became old enough to talk he wanted a play kitchen and a pushchair to push his soft toys around in and a tea set, but he felt annoyed that everything was pink "thats not for me" he would say, he did get a red play kitchen he was happy with and a tea set.
now where did he get the pink colour is not for me thing from? I assume TV as no one said anything to him and he wasnt in preschool. later on he developed an interest in trains probably because his grandfather is a train buff, he still loves cars, loves cooking but later lost the interest in trains.
he has developed an interest in nerf guns now which is because of me, he used to find them frightening and had no interest in them, I bought myself a Xshot vigilante for christmas and have now had to buy him a xshot harwkeye we both like shooting targets with them its fun.
so he is prove that everything is led, if he didnt have such a laidback parent it would be very easy to see the wanting a pushchair, kitchen and tea set "to be like mummy" being seen as somekind of milestone and steering the child from then on, or even doing so before without realising it like if mum really wanted a girl, or dad really wanted a son and if there are other children of other sexes that are treated differently in the family.
