I switched my own son to Dr. Brown's bottles when he had gas/colic issues and omg, it was a WORLD of difference!!! I hated washing those damn bottles but they were well worth it. I even tried to go back to regular bottles one weekend thinking he was a little older and could handle it and by Sunday night my DH said HE would wash the bottles if I'd please go back to the Dr. Browns!!!
So I wouldn't have an issue with a parent using them but as a daycare provider I would either 1. wash thru dishwasher or 2. send home to be washed.
I would not allow the facetiming - so I can deal with a screaming baby after mommy hangs up?? No thank you. I have no problem sending mom a text or a picture here and there to update on child's day but no way am I playing with baby's emotions where they can see mommy for just a few minutes. No way!
