Hate seeing Boo ill :(

So on Monday night Boo started throwing up, after a very disruptive day on Sunday as I ended up in a&e, and we ended up in a&e. She failed the water test and barely drank anything all night. They put a drip on her for 4hrs until we were transferred to another hospital that had a bed for Boo.

While there she managed to drink 6floz which is much lower than her normal amount. They did all the test and said that she was slightly dehydrated as her wee was very yellow and strong smelling but she was 'well' in herself and Tuesday evening we were discharged. Got home and she had another 3 floz but also had some diarrhoea. Last night I managed to get 3 bottles (7floz) overall into her but this morning again she has the diarrhoea. Trying ORS with her but she doesn't like it and she just wants to sleep. Gonna see how she is tomorrow before going to the doctors again. Hate seeing her ill.

Any advice about how to get her to drink more or how long this bug might last?

First time mum so probably over thinking everything.
