Catherine and her son and heir Paul maintained a distant relationship throughout her reign. The aunt of Catherine's husband, Empress Elizabeth, took up the child as a passing fancy. Elizabeth proved an obsessive but incapable caretaker, as she had raised no children of her own. Paul was supervised by a variety of caregivers. Roderick McGrew briefly relates the neglect to which the infant heir was sometimes subject: "On one occasion he fell out of his crib and slept the night away unnoticed on the floor." Even after Elizabeth's death, relations with Catherine hardly improved. Paul was often jealous of the favours she would shower upon her lovers. In one instance, the empress gave to one of her favourites 50,000 rubles on her birthday, while Paul received a cheap watch. Paul's early isolation from his mother created a distance between them that later events would reinforce. She never considered inviting him to share her power in governing Russia. And once Paul's son Alexander was born, it appeared that she had found a more suitable heir. The use made of his name by the rebel Yemelyan Pugachev, who impersonated his father Peter, tended no doubt to render Paul's position more difficult.
