Stopping expressing before DD has dropped feeds

[CityDweller]

I express at work and I'd like to stop - DD will be 1 yo shortly. However, she still takes two (relatively small) feeds of ebm during day while we're apart and shows no real signs of giving those up. Up to now she has dropped feeds of her own accord and at her own pace. I'm planning to continue feeding during day when I'm with her, but want to stop expressing/ providing ebm on days we're apart.

So, what should I do? Just have childminder offer extra snacks in lieu of ebm? If so, do I do that cold turkey or one feed at a time or gradually reduce the overall amount of ebm I send with her to cm?

What did/ would you do?

the childminder could either offer snacks or could offer a small drink of cows milk instead of breastmilk.

Yes - I guess it's not particularly complicated! I think it's more about me feeling guilty, actually - switching her on to something less nutritious because I don't want to pump anymore. But presumably most people giving up pumping at work at 1yr? I think I need to get over myself...
