To know the time pattern

Today my spouse and baby left the hospital where they've lived for the last five days. It was the first moment the baby experienced the outer world out of the closed secure environment. Unfortunately it was a chill snow day.

The baby seemed to be confused when he arrived his grand-parents' home, in which they will spend the next month. He made me change his diaper a dozens of times. I became aware that the most inportant thing we should care on changing diapers is to know the time pattern.
