How quickly does a 2-year-old dehydrate?

[Lawks]

Dd is 2.8.
She was absolutely fine all day until about 4 hours ago when she was violently sick. She has been sick about 20 times since then. She is sipping water but can't keep it down. Apart from the water which she keeps losing she is dry heaving and losing bile.

In between vomiting she is droopy and a bit pale, but okay. She's watching tv and complaining that he brother wants to share her blanket.

We live in a warm country but have whacked up the air conditioning.

I'm inclined to let her sip water all night and see how we do, and reassess in the morning (we're 4 hours ahead so it's bedtime here). Dh wants me to check with MN whether we should pop her down to the hospital tonight.

What is her temp?

Sorry, meant to say. 37.5.

Is she weeing? Dry mouth? Sunken eyes?

It takes hours (about 24) but it depends on a number of things. If she doesn't wee in 24 hours then take her, if she's drowsy, has sunken eyes and a dry mouth.

Get her to sip some lemonade or squash, this will help. Cup full will make her vomit so little bits often.

Do check her temp.

Sounds like a tummy bug. Any abdo pain?

Keep sipping water and check on nappies if she doesn't wee for 6 hours she is becoming dehydrated and needs to be checked out now, Signs of dehydration include:

Dry, cracked lips
Crying without tears
Faster than normal heart rate
Listlessness
Decreased urination

The above are the early signs that indicate you need to up fluids and get her drinking electrolyte drinks

Signs of severe dehydration which require urgent medical attention include:

Reduced skin elasticity or wrinkling of the skin so when you pinch it it doesn't smooth
Sunken eyes
No daytime urination for 4 or more hours
Extreme fussiness or sleepiness
Coolness and mottling of hands and feet
Decreased capillary refill time - to check this, pinch then release a toe or finger. If it takes 2-3 seconds or more for normal color to return, the child is dehydrated.

Useful posts. Thank you.

Dry, cracked lips - don't know as she's eating an ice lolly.
Crying without tears - not crying.
Faster than normal heart rate - ?
Listlessness - yes she's listless.
Decreased urination - that depends on whether the puddle on the floor earlier was a spilled drink or a wee.

I'll keep an eye.

I got worried earlier as it was 37 degrees here today, but now it's night time and the air conditioning is on it's actually no different to being ill back in uk. She's poorly but not worryingly so atm.

Would apple juice do the same job? We don;t have any cordial in.

I have ice lollies made with dilute apple juice (which she's having now) or sticky sweet guava juice cartons.

yes, anything with some sugar in it, it'll keep her alert.

Poor baby didn't keep the lolly down for long. Ahh, she's cheerful enough between chunders.

Sips. A few ml at a time.

Hope shes starting to feel better

She slept okay last night and was doing really well today. Eating cautiously, no vomiting, even went on the trampoline earlier. Got ready for bed. Threw up EVERYWHERE. Poor lamb. I think it's a bug.

DH is sick too and hasn't managed to peel himself out of bed all day except to sprint to the loo and totter back.

Am just waiting for ds to start to declare a full house.
