Ahh... a BIG difference. A large family with 6 or more children are more independent and learn things quickly. I have friends with 4-6 children. Their kids are independent, could take care of themselves, bath, feed, play, go to school by bus, learn to ride a bike without parents help and many more. They have older siblings to teach them and parents are more relax because they "hand-over' their tasks to the older kids. While small family like mine, 2 kids, rely too much on parents , not independent and until now, my younger boy; 6 years old, doesn't know how to ride a bike nor play badminton. we parents pampered them too much, worried about them although our expenses are low compare to my friend with 6 kids!!
