Loving the Smartipants but nights are still wet

I am still loving the Smartipants they are working great for both of my little ones during the day. However, my daughter is a heavy wetter and she is waking up wet even with the diapers double stuffed. I really do not think that the Smaritpants covers can take three inserts, as it is really snug with two.

I have heard many different solutions, and successes with different types of diapers. I am wondering if moms have a day time and a night time stash. As I am still fairly new the the cloth diapering , this had not occurred to me before now. I am getting a Bum Genius 3.0 pocket from Kelly's Closet and give it a try. Maybe this will help with out night time situation. If it does I may buy a few more for just night time use. Though as our funds are currently low that may have to wait.
