I think parents are always doing their best for their kids whichever way they choose to parent.

It is the hardest job in the world.

As parents don't we all want the best for our kids?

Co-sleeping is part of the idea of instictive parenting or attachment parenting (AP). So there is no prescribed time that you have to do it. You do it as long as it's comfortable for you, the child, the family. It promotes prolonged breastfeeding among other positive consequences.

My husband and I co-sleep with our 15 1/2 month old son. For us, the decision is that Matthew will start to transition to his own bed when we find out we are pregnant with our second child (which we would be trying for by early next year). Some parents co-sleep up to 2 years and beyond. Like I said, it's all up to the family.
