This is a while ago now, but I ran into the same issue. We did glass bottles at home and at daycare for a while, until the day my daughter yeeted her glass bottle onto some tile and it shattered everywhere and the daycare immediately implemented a new "no glass bottles" rule. I ended up finding that playtex still does their "drop in" bottles - the ones that its just a hard plastic shell and then you'd drop in this plastic baggie thing? Well now they have silicone drop-ins. https://www.amazon.com/Playtex-Baby-Reusable-Breastmilk-Collapsable/dp/B0CK55CRC3/ref=sr_1_1?crid=2PKJF5CXTV7RU&dib=eyJ2IjoiMSJ9.DyloQOxlj8yAn-cwIgwa2o3CMbvf4ipljcjxt0LyxepV5Rd1A7UjBqfKfZ1YhmKW5nYjaOgePpOWpLa8qvf2YZva7kIQGNmVcaBtmfyruuncO8zoIge3Ca4moMXtzIOMJEhIOe_0SuoNUhq4t143k1G3eokM3J-Wc6N6XEJxXRtY2gKXbbXIjQiWIt34IxG8jcKfsn3AhbHvumF4CQeLEcSyAGrk6otAH5ynUiCRjiBgVT0qkQSlkigFz_eJo4Fml_47urROVnvyryu4Sx1TC44k99LgvaP5GBnKGrjtBh4.M30wK6fynRFba7C3vs1ODypUZ_NibKbLe2UZ2F9dW0Y&dib_tag=se&keywords=playtex%2Bdrop%2Bin%2Bsilicone%2Bliners&qid=1782500073&sprefix=playtex%2Bdrop%2Bin%2Bsilicone%2Bliners%2Caps%2C143&sr=8-1&th=1 That worked well for us - they are transparent so you can see how much baby ate, dishwasher safe. Also if you are pumping apparently you can pump directly into the drop in pod thingies. Since you're only going to use these at daycare, its also a lower investment. Set of 6 pods + 3 bottles w/nipples will run you like $55 instead of $25-$30/bottle.
