I really think that most couples push out babies is because they think that they are expected to: it's 'normal', our parents want a grandchild, let's keep the family name going, they smell nice, they'll look after us in our old age. We have never had, as a choice, children and have had a great life and still are. I listen to my other family members' and friend's stories about raising kids and I'm quite happy not to have had any. Of course, people with children are going to vehemently disagree with me but then they have to don't they: they can't send the kids back!
