Am I in the wrong??

My husband and I have a 3y/o and a 9m baby. He likes to stay up late and play video games when the kids are asleep.

Well this morning I woke him up at 9. I was up with the kids at 7, like every morning. He said he had a headache, popped an ibuprofen and went back to sleep until 10:45.

At 2pm he asked me if I could watch the kids so he could have a break and play video games.

I asked him “when’s my break??”

He said “whenever, just ask.”

I feel like he gets mad when I ask him to watch the kids.

Now he’s in a horrible mood. Was I wrong?
