I put my son in a SuperYard play den when I need to shower, clean, etc. He's a year old and miserable in it. He cries and holds on to the sides the entire time he is in it. He now shakes it and can even lift it slightly of the floor. I need any suggestions as to how to safely contain him because I'm sure it will get worse as he gets older and stronger. Also, the SuperYard is recommended up to two years of age. What do you do at that age so mom can get things done?
