Night Time Diapers

Hey all,

My LO just turned 2 years old. He is a big boy. I've tried to potty train him since this pandemic has left us homebound for a long period of time but he just isn't ready yet. He is currently using size 6 Huggies night diapers. He is a heavy wetter at night even though I stop fluids by 6pm. He doesn't take a bottle he just sips water and milk through out the day so I don't know why his diapers get so full at night! He has been peeing through even the Huggies night time diapers at night and is waking up soaked. Is there any other option out there? They don't have a size 7 in these diapers. Any recommendations would be amazing! Thanks.
