Tips for getting 1 year old off bottles at daycare?

Am

My daughter only goes to daycare twice a week so she’s use to having my milk whenever she wants it the rest of the week. She will only drink it from a bottle at daycare and will refuse it from a sippy cup. I really don’t want her to keep using the bottles since she’s over a year even though it’s only two days a week. I don’t think she’ll do well with not having any breastmilk the whole time at daycare so I’m still sending it.

I want to be able to continue breastfeeding her when she’s home.

Anyone have any tips on how to get her off the bottles those 2 days? She gets plenty of regular food but still wants her mama’s milk.
