This is what I used to do with H when he was deep in the fog. I made a schedule with him. You watch the kids from 4-6pm Mon-Fri. First week he missed certain days. I stayed quiet.
Next week I pulled out the schedule and repeated myself. You watch the kids from 4-6pm Mon-Fri. He agreed. I asked, will this be a problem since I noticed you didn't do it everyday? He claims no it won't.
Following week the same thing.
I slowly included 8-9pm Mon-Fri since I needed help putting kids to bed. Then Morning 7-7:40am.
It took a good 6 months before we had this schedule down. The kids expected him in the morning, after he got out of work and before bedtime.
I was very careful not to criticize him about this but praise him constantly on what a great dad he was! His LL is WOA.
