DD turned 12 months yesterday. What do I do now?

I've been doing 2x/day pumps at work, and nursing morning/night/weekends. I plan to continue the nursing indefinitely.

We have given her some WCM and she seemed to like it okay, but didn't guzzle it. I have a freezer stash but I hope to donate most of it to NICU babies.

Do I keep pumping once a day until she starts to really eat a lot of WCM? Drop pumping completely and start giving her frozen breastmilk until the WCM is providing a cornerstone of her diet?

How does this work.
