As I observed this I wasn't sure if he knew the toy was underneath or if he just wanted to pull the fabric. I repeated the same task two more times and he was no longer interested. He failed to find the toy twice after the first trial. After that we gave him a little break because he started to get annoyed. The third test I did was the A-not-B task which involved two identical cloths and an attractive toy. I got the baby interested in the toy and hid it under one of the blankets. I repeated this three more times so the baby could see, then I changed and placed the object under the other cloth. The baby was just giggling and laughing and started tugging at both of us
