Here's a sure-fire way for kids to get their parent's attention. Parents will LOVE this and thank you for sharing it.!!
When Mom or Dad are on the phone or talking to another person, and the child wishes to get their attention, the child comes up and puts his hand on the parent's arm, or shoulder, etc. without speaking, tugging, jumping up and down, etc. (See picture) Now the parent is aware that the child needs something, but she can finish his or her thought and then turn and acknowledge the child -"Yes Johnny, now what can I do for you?"
This was taught to us by a parent years ago, and we've taught it ever since.
