3 Minute Rule with Kids

Mummies, do you follow the 3 minute rule with your kids? I just read about it now. It seems our children will start trusting us more and feel more secure with us if we follow this 3 minute rule. It's very simple. Make sure to spend those special and crucial 3 minutes exclusively with your child every day when you come back home from work/outside and after you pick him from school/childcare. Hug and talk to them and remember to be at the same eye level as your child. I'm going to start doing this from today. What do you all feel about this rule?
