The families I work with find this idea highly effective. This comes from the book "Transforming the Difficult Child" (By Howard Glasser and Melissa Block). Parents report that when they make time for special time with their child(ren), childrens attention seeking behaviors decrease, children do not feel discounted when parents are busy, and parents do not feel guilty when they have to say, "I can't right now, I am tired, but I'm looking forward to our special time." Give it a shot!
"Special Time" is a regularly scheduled time. Think 15 minutes each day. Let your child(ren) know that you would like to start having time for just the two of you and you can come up with a name for it together. Explain to them it will be the same time each night and it will be for about 15 minutes. During the 15 minutes the child can pick the activities (talking, playing with toys, reading a book together, or a short game are the most common). When the time is up, let them know "Our special time is over for today, I look forward to tomorrow's special time.
Things to think about before you start:
1) Make sure other children are supported during this time as not to get any interruptions.
2) Turn your phone off or if you have to have your phone on and it rings during the special time come up with a plan to handle the call and not interrupt the special time ("I'm sorry I can't talk right now.")
3) If you choose to spend more let your child know that the special time is done, but your willing to stay a bit longer. The child does not add on time you do.
4) This time is never taken away for bad behaviors, homework problems, etc...
5) This time is not for discipline or reviewing of the day.
Finally, its not the amount of time it is the quality. Children feel special when they know that time with them is as important to you.
