My daughter has only recently started sleeping through the night at 15 months. She is a very, very heavy wetter, and will soak through the microfiber (not the greatest, I know, but all I could afford at the time) inserts and soaks her bed and wakes up at 4 AM in need of a sheet change and a bath.

Since this started becoming a regular occurrence of 4-5 times a week, I have started putting her in night-time training pants.

Does anyone have any reccomendation for a good insert, pocket diaper, or AIO diaper to use for overnights with a heavy wetter? It's a worthy investment since she will probably be in the diapers for another six or seven months, and her little sister, who could be born any time now, is also going to be in cloth.

She is also a really large kid and wears the 3T training pants, if that makes any difference. Her daytime cloth diapers are currently Bum Genius pockets, Charlie Banana pockets, and Alva pockets. I would prefer not to use prefolds because she hates diaper changes and fights me through pretty much every one, so the less complicated the better.
