When to start pumping? 1st time breastfeeder

Amanda

Hello. I am due in 12 weeks with my baby boy and and in planning on breastfeeding which I never did with my 1st 3 babies. I have a pump and plenty of bottles and bags for storage, etc.

My real question is I will only have 8-10 weeks before returning to work and I want to make sure I have a good solid stash of milk when I do go back.

When is a safe or good time to start pumping and storing breast milk? Soon as my milk comes in, a couple weeks in?

At each feeding on the boob baby isnt feeding from?

So clueless to all of this and I just want to make sure I can be as prepared for success as possible.

Thank you for any input or advice you experienced moms can give me
