About a month or so ago, my son started the phase of saying daddy said yes or mommy said yes if the other one of us says no. He's too young to ALREADY be trying to use this tactic to get his way, don't ya think? He's only 3!
Sometimes when he does this though, hubby and I are BOTH standing right there so we hear each other say no and KNOW that no one said yes. One of these days our son will realize he actually has to have us in separate rooms for this tactic to possibly work. Lol.
