How do you keep your children quite while your on the phone?
The truth is, I don't. This isn't my area of expertise.
But, I did try one thing that worked for awhile, and I can at least share this silly idea (warning: it is pretty silly)...
I invented a secret code - its more fun for your kids if they are in on a conspiracy. The plan was, if I was on the phone and they needed me, they could come and put their hand on me knee. This was the signal, and if I noticed their hand, I would tap back. The tap back would mean = I know you want to talk to me, but I am on the phone, so when I'm off I'll come talk to you. If it was so important they couldn't wait then they would keep their hand on my knee and I would keep tapping which would mean = I know its important, I am going to hurry and finish talking. The secret code worked for awhile - but that's all I've got.
