The stages of growing up

Adults are funny creatures. They are so fixed on these things they call milestones. When they see an infant, the second question they ask is something like this: Does he hold his head up yet? Does he smile yet? Does he do this? Does he do that?
Someone should tell them that this puts a lot of pressure on the little infants to catch up with these expectations. But I have to add that we infants don't care that much about this. I know infants who have mixed up the whole milestone business by doing things in reverse order, like sitting before rolling over. In fact I am going to do the same thing.
