Question about weaning...

My baby is almost 1 year old and I’m going to start weaning some. I’ve had a massive oversupply the entire time, so my freezers are full, and I have questions about what weaning is going to look like. I want to continue to feed him when he wants, I just want to drop pumping at work.

I’m wondering if I drop pumping at work and just use my massive freezer supply for daycare, would I totally loose my supply? I want to keep feeding him in the evening after work, bedtime and morning until he’s completely ready to be done.
