18 mo old with fever, diarrhea, vomitting

Hello,

My 18 month old daughter has had the following symptoms since mid-day yesterday. I believe it is a virus she caught rather than something she ate as my husband had a light fever and stomach flu last week.

Diarrhea - has had it about 4 times between yesterday afternoon and evening, within half an hour of eating, but not at all during the night. Then had a big bout this morning after she woke up (before eating anything). It's slimy, yellow/brown with some lumps. Yesterday had some white mucous but not this morning. She doesn't seem to be in pain while she's expelling.

Fever - she started feeling warm before the diarrhea, but the fever has been on and off since then. She's definitely warmer at night and when she's asleep.

Vomiting - she threw up profusely around 2am, 5 hours after her last bottle. It was all sour curdled milk. Around 5am she woke up, cried and then started heaving, but nothing came up.

Sleep - she wouldn't sleep till after midnight, after that she was restless all night, like she couldn't get comfortable. We had to hold her all night, she'd cry as soon as we'd try to put her down.

Appetite - has been normal since this started. She had some solid foods from our plate before her bottle last night and then had almost her full bottle for breakfast this morning and went back to sleep.

Fluids - she's very thirsty and drinking a lot of water, and doesn't appear dehydrated. She urinated last night and once in the middle of the night. I'm not sure if she did this morning.

Mood - she was in a normal (happy, playful) mood till bed list night, then she cried and and was restless till midnight. She's never like that, usually goes right down to sleep. She cried for about 10 minutes before she vomited last night, and again before she started heaving. But once those episodes were over, she seemed back to herself - calm, curious, easy to laugh, though tired and a little dazed.

Any suggestions greatly appreciated!
