How do I become more patient?

So my husband and I have a good relationship, he’s my best friend and I love him so much....but I find myself quickly becoming impatient with him when it comes to taking care of our daughter. For example, tonight I was finishing my dinner but our daughter had started to fuss. He volunteered to feed her. So I’m like okay cool. But then he takes his sweet time, like picking up water bottles out of the cup holders on our sectional and slowly making his way to the kitchen to throw them away...all while our daughter has gone from being a little fussy to going into complete overload because she’s hungry. He still takes his time. I glanced in the kitchen, he was looking at his phone so I got up and started making a bottle. He got so mad at me and told me I don’t respect his parenting. He also said that our daughter is the way she is (fussy?) because of me...(but actually we’d been running errands all evening and she’s hungry now). I don’t want to make him feel stupid or like I don’t respect his parenting. How do I go about being more patient? What are ways I could go about hurrying him along in situations like that without making him so upset? Am I over stepping my bounds? Our daughter is 11 weeks old, I don’t let her cry...especially not if she’s hungry so I’m not sure what I could have done differently. I wasn’t nasty or mean about feeding her, I was just gonna do it. 🤷🏻‍♀️
