Touch her shoulder and repeat her name gently. This simple physical action helps her learn that when you call her name, it is a request for her attention. Expecting to gain a young child's attention by simply calling or yelling her name is not realistic when the child's attention is elsewhere. In fact, calling your child repeatedly without making any other effort to get her attention may teach her to ignore you. Once you have your child's attention, speak simply.
Young children have very short memories.
It's hard for them to keep in mind more than one direction at a time. In this situation, your child may put his blocks up but then start playing with something else because he forgot the other two instructions. Or he may just remember the last instruction and come sit at the table without cleaning up. Instead, focus on one instruction at a time. Daniel, it's dinnertime.
