potty training before 1 year

My husband gets really annoyed when he sees our child wetting the bed or when I ask him to help change our child's diaper. Our child is only 11 months old. Isn't that normal? Because of how annoyed he is, he's now often trying to teach our child to pee in the toilet. He holds him like that. I don't like seeing it... like... why can't you just accept that our child is still a baby and isn't at the stage where he can signal when he needs to pee yet? Is it safe to do potty training at that age?
