Nursing question

Megan

So my baby just decided he’s done nursing 😂😭 I was hoping to nurse him until 18 months but about 5 days ago he just stopped. He will legit cry and hit my chest if I offer it to him but will take a bottle beautifully. So for the last few days I’ve been pumping but my supply has gone way down because finding time to pump has been difficult. That being said I’m only pumping about 4-6 ounces every 12 hours. At what point do you think my supply is low enough to just stop? I’m fine with stopping. I hate pumping and honestly we are leaving for the beach in a week and although I wanna keep my big boobies I don’t want to drag my pump onto an airplane with me. Does anyone know how low you should get your supply to drop before you can stop altogether?
