That was the issue with the one I described above .... Non stop and didn't listen to anything and figured if he could do it then it was okay ... First day here he scaled my staircase on the outside got up on tables and jumped off same with the back of my couch ... So I had to go all hard core on him and he is required to be in his playpen during nap tine whiter he wants to sleep or not and he could never be trusted at this point to be on a cot. Some children just need a firm hand and this is one of them ..... The parents say how much better he is now and is actually a joy to be around .
