7mo: no appetite and won't drink

[DullWomenHaveImmaculateHomes]

She's getting over a cold during which time she lost her appetite. She still hasn't got it back so most of her feeds are bf with a bit of bottle because I'm not producing as much as I used to.
She was just starting to get into drinking water out of a beaker (she doesn't like it in a bottle) but now she's not really up for it. She hasn't had a wet nappy since I got her dressed this morning so I'm worried she's not getting enough fluids.
Should I just keep going on the milk or push the water a bit more?

DD is the same at the moment. She has bronchitis and has no appetite. I cant force her to take her milk or water(lips of steel) so we are continually offering it to her in the hope that each little sip adds up over the course of the day.

Also we are using watered down apple jiuce as she loves it and am hoping the sweetness might tempt her to take more.
