Where do kids hide car keys?

My 20 month old twins were playing with the car keys last night and they are now no where to be found. The husband had to take a taxi to work today and is supposed to go to a party tonight -- looks like he'll be taking another taxi! Unluckily, his wallet with his cash and ID are all in the car...I've checked everywhere. The fridge, cupboards, trash, closet, toilet and wherever else but the keys are gone!Where have you found all of your lost items? I've checked all their previous hiding spots but still, nothing! Trying to get some ideas here. Thanks! via /r/Parenting http://ift.tt/2u83GDr
