My baby is 5 weeks old and hasn’t been alone with his dad for longer than an hour (and even then, I was just in the next room sleeping).

I exclusively breast feed and I’m home with the baby day in and day out. He cries all the time, it’s just what babies do. Well he’s been crying for about 10 minutes on and off and my FI is already getting really annoyed with him. I go back to work in 2 weeks, and FI is going to watch the baby for 1-2 days a week. I’m worried about how he’s going to manage for 8-9 hours if he loses his patience in 10 minutes. Any suggestions? I don’t think he’d hurt the baby but I know how easy it is to get angry with a screaming baby.
