That's grown up of her !!! I only rinse bottles and put them in a bag to go home . I also do my own thing in my dayhome . Meaning I have two doc siblings who brought special sippy cups to be used here and I use ikea cutlery so I stored them and use my own .
I only have one on bottles , same idea , very picky , undersized and I only give bottle after lunch and after nap . In my opinion , this dcg at 22 months , the bottle is ridiculous ! Young mom who says dcg gets so upset without it , not here though !!
As she has left , it's not your problem anymore , !!
