Or maybe had them and thought that Jesus being the sweetest baby wouldn't wail and keep his poor parents up all night going...
Is he hungry?
But we just fed him.
Maybe he's wet?
No the diaper is dry.
Maybe he has a fever. Does he feel a little warm to you?
Maybe he is too cold.
Oh I hope he is not sick...
Until five minutes before dawn when the little darling will give a belch that rattles the windows and promptly go to sleep. Leaving the parents to face the new day with no sleep....
But that is just a guess.
