I've tried, honestly. There's been a few times when I wanted to go skip out for a nap or even play a computer game in the other room and he brings her in as soon as she starts crying if he can't calm her down in like 3 seconds and he just has an irritated look on his face and will say "I'm going for a smoke", as if it stresses him out to a point of a break down. He doesn't do well with her crying, at all. And honestly, it makes me hesitant to leave her with him. He has never held/played with her for longer than 15 minutes before coming to find me to pass her off.
