Dear D.,
They sell a product called diaper doublers. It is on the order of a sanitary napkin, however it is great added support for night time. You may want to consider an overnight diaper, pull ups are not really made to be super absorbent since they are intended for potty training. My son was potty trained at 2 1/2 however he wet the bed for many years after that so I know what you are talking about. I tried everything from limiting fluids, to bringing him to the toilet before we went to bed and nothing seemed to help. He just had to grow out of it on his own. I think Stop and Shop carries the diaper doublers if you do not want to go back to diapers. Good Luck
