At a loss....need some advice!

[Bookworm]

Okay, just to add something. She just woke up from her nap. Since she has not eaten or had anything to drink all day here, I just made her a bottle and lied her down on my floor with her blanket and bottle and she is now drinking it. I normally wouldn't do this, but her mom did this to her one morning at drop off so she could finish her bottle. Should I allow this to continue so she will atleast stay hydrated here? I don't want to do this when the other children are around, but I just can't not have her eat and drink here, can I?
I have tried giving her a bottle at nap time as that what she does at home, but she always refuses it, so I am at a complete loss on what to do...
