How to combine Buddhism with being a parent?

Buddhist philosophy says that we shouldn't get attached and try to form bonds with something and desire or crave it because everything is essentially impermanent and this will lead to suffering. But how can you raise a child without being attached? Wouldn't that make you lousy parent? Of course the older a child gets, the more you'll have to let go. Every child needs to find his/her own way in life, but that doesn't take away the fact that, especially in the early years, there is a big attachment to your children. Perhaps I am misunderstanding the concept of attachment? Or is there another explanation?
