I would say yes...BUT before you do...double check the dehydration first.
- How much is your little girl actually drinking? (In oz?)...Hot weather (well, for seattle) came on about a week ago. 40 oz (essentially two small water bottles) is pretty bare minimum for small children in hot weather. Double or triple that is frequently needed to stave off dehydration. In reeeeaally hot weather (with any activity) she should be drinking *constantly*. Fortunately, we don't usually get into the 90's low 100's...but even in the 70's/80's if she's active she should be drinking at least 20 ounces every 2-3 hours or so.
- Single Mum...so daycare? How much is she drinking in daycare, and do they play outside? And is the facility air-conditioned or not? I know preschools where the kids are required to have water bottles (and the numer of them that they drink in a day is written on a piece of tape so that the parents know...and others where they only have teensy tiny shotglass size cups of water/juice that they're only allowed to have during certain times...and still other's where it's line up for the water fountain and they're lucky to get a few swallows/gulps before being jostled aside, or told to move to let someone else get a drink. If she's pounding the liquids as soon as she gets home, pretty guaranteed that she's not getting enough in daycare.
FYI...Although you may well know this already:
- Yellow pee is dehydrated.
- If you can pinch the skin on the back of her hand/wrist and it takes a while to go back down then she's SEVERELY dehydrated.
If she's fine in the hydration department (and you haven't been eating asparagus all week;), then I would definitely take her to the Ped tomorrow...and if she's severely dehydrated...call tonight for a touch base & check on best way to rehydrate as quickly as possible. SOME forms of dehydration are best fixed with an iV in the office...but most are easily handled at home. The nurses hotline at Childrens' or Evergreen would be able to steer you in the best route.
Good Luck :)
