I have it right in my contract that I do not accept glass bottles. My kitchen is ceramic floor and all food is eaten in there. Since babies are close to a year old when they start they should be sitting in a chair using a cup for most of the feedings or at minimum holding their own bottle.

There are plenty of non breakable BPA free options out there. There is an entire "born free" line that most of families use.

I also figure it is incentive for parents to get them off the bottle if they are so concerned. But they will be going to a plastic cup from the bottle so the whole glass bottle debate is something they can do at home and have one plastic bottle to leave at my house and then I will transfer milk as required.

When I had my first all bottles were glass and were sterilized, etc. It wasn't until my second came along there was even such a thing as plastic bottles and clear nipples and well anything that hadn't been around for the 30 years before that. Because there are options I insist that parents use them. The same as I insist on velcro shoes even though there are tied shoes available.
