DH is 4, was delighted with his Santa presents, then as is the way opened a few other presents from under the tree from friends and family before had to leave the house to go to inlaws for lots more opening of presents. We nipped home again briefly and he's asked to open another present, which I refused, telling him he could open the rest tomorrow. He accepted this without discussion but DH has now said I was being mean....was IBU?
