Continuing to pump after transition back to breast

Sara
My little girl was born at 37 weeks and after a week in the NICU being bottle fed, wouldn't breastfeed. She's 5 weeks now and I've been exclusively pumping and bottle feeding breast milk. However, as of 24 hours ago, she's been fully feeding from my breasts. I'm hoping it continues! Here is my question. Do I need to continue to pump at this point? Can I stop pumping and simply let her feed instead? Will my supply drop or will I risk losing it? If I do need to keep pumping, how often?
