By using this pad, we have managed that our son, now 4 months old, wants a little longer lie on your stomach with each passing day. When he starts to complain about, we put it on the pillow and then he's distracted immediately and plays with the moored figures. So we have the time spent on his stomach - can increase already 4 minutes more than 20 minutes =) I find this pillow just great - without a pillow.
