Any Bed Wetters on a Monday? Lol

So I keep trying to give my BD a chance to put the freaking diaper on right at night before bedtime so my girl won't have an accident and it's like he can't get it for the life of him. So when he goes to work, I'm the one that cleans up all the pee on the toddler mattress. He should already know how to put the diaper on and I think he is just getting lazy. Do any of you know what works best on trying to get pee out of a mattress? I've already tried using vinegar and baking soda. Is there something better out there? Also I welcome any suggestions on like a sleeping mat that soaks up urine that is super easy to clean in the morning. Thanks in advance 👍🏻😂😒🤦🏻‍♀️
