I’m sorry you feel this way! I went back to work at 4 months and I pumped 3x a day, 5 days a week until I quit my job when he was 16 months. It was hard, and exhausting washing bottles and pump parts everyday but I’m glad I did it. He’s 20 months and still nursing 😊 If you want to transition, you’ll probably have to mix the breastmilk and formula for a while til he gets used to the taste. Or try to stick it out til he’s 12 months and see if he’ll drink cow’s milk. My son won’t drink any milk besides mine. My daughter was the same way, wouldn’t drink cows milk til she was done nursing at 2.5 and it had to be chocolate.

I’ve heard of people doing 90% breastmilk 10% formula then gradually changing the ratio until it’s all formula. Not sure if you’ve tried that, but it could help make the transition smoother. Good luck!
