Does an overnight size 2 Pamper exist? Other questions

Nessie82

LO is in size 2 swaddlers and for the past few nights he has woken up with a leak in the same spot. He recently became a side sleeper and this is the same side he has had the leak on.

Is this a coincidence?

Does a size 2 overnight diaper exists? (we have only used pampers and I'm afraid to try a different brand because LO has not had a any rashes with the swaddlers.)
