When the ideas of attachment parenting were being developed in the 1960’s or so, the advice was fairly ‘gender neutral’.

Later however data started to accumulate that baby boys’ needs were different from that of girls. Not qualitatively but quantitatively. Male babies on average have greater difficulty self-regulating their emotional state and therefore have a greater reliance on emotional support. They need it both more intensely and for a longer period than girls.1

In essence, mothers need to work harder with their boys than their girls.2

It seems that that boys’ brains develop more slowly3 , and are more vulnerable to negative outside influences, possibly as a consequence of the presence of the male hormone testosterone.4,5

So here we have a double whammy. The very babies that our culture says have to be brought up to be tough, who should ‘man up’ and not show their emotions, are precisely the ones that are harmed by that attitude.

If you want your boys to grow up to be brave, secure and exploratory but empathic and caring, allow them to remain babies for longer.

Mothers often know this at an intuitive level but sometimes the father does not. And he really needs to know.
