How do you find time?

I have a newborn. My fiancé and I are taking shifts but I’m suffering with mine.

His shifts consist of: calm the baby, feed her a bottle, change the baby. She generally lasts 3 hours before asking for food with him. He seems to get lots of time to do his hobbies and bond with her.

Then for me I have to: express milk (20 mins), give bottle, breast feed (10 mins), change baby, calm baby (and I can never do it). And she tends to want a feed every 2 hours from me.

I’m so exhausted during the night that all I want to do is sleep. Or just take care of myself a little. But I can’t. Because she demands me.

I don’t know what to do to make my time less miserable and hopeless feeling.
