Can we see the act of giving birth as a compassive one?
When a serious couple is raising a children, they will take care of their child, will give education to her, love and the cares the he/she needs. If the couple (or someone in the couple) is a buddhist, raising a soon is giving an oportunity for another being (that just died and will rebirth on that family) to take contact with Dharma. And that is something very precious. So, i think that giving birth to a child can be something good ,specially if that new born being can get such an opportunity (contacting/learning Dharma).
What do you think?
Whether the child really takes a serious interest or not depends on their dispositions.
I reckon there are a lot of kids tossed into monasteries around the world who would rather not go down that route if they had the choice. It is really just for the parent's own satisfaction to dress the kid up in some costume and fantasize what kind of merit they think it is.
Even if you don't force feed Buddhism to the kid, it is still up to them whether they really take to it or not.
At the end of the day though go to the zoo and you can see plenty of animals able to procreate and look after offspring. Making kids and raising them is an entirely mundane affair.
