My 19 mo and I like to visit grandma but the nap is hard if we are out. He will only sleep in his crib at home. Very rarely will he even sleep in the car. We love to visit grandma but I feel bad not to put him down for a nap and just expect him to happy and playful. Is it bad to once in a while if we are not home to not give him a nap? I guess I might just put him to bed a bit early. ?
