Do use bleach water, one tablespoon per gallon of water, let it sit for FIVE MINUTES, then wipe/rinse, but don't go stronger on the bleach. Using more bleach won't help or kill more germs. It is the five min that is important, not using more bleach.
Make the kids sing a song while washing hands. They MUST rub the suds in for twenty seconds to get rid of germs. So sing one round (one animal) of Old MacDonald or other kid song as you rub the soap in. This is a good rule for always, and is esp important for when you are sick.
While jello is common as an aide for upset stomachs, the flavors and colorings in it can be hard on the system. We always use plain gelatin and apple juice or even gatorade for the liquid. It works well. Pedialyte for the little ones is vastly better than pediasure. It has what they need to get through this, and the pediasure will make things worse for most kids. Slimfast is the WORST when you are sick. It is pretty hard on the body.
If at all possible, ask the doctor for phenergan gel. It is a rub on version of phenergan and is a big help when you all have a virus. You will need to call around to find a pharmacy that carries it because it has to be specially compounded, meaning the pharmacist mixes it up at the store rather than ordering it from a supplier. Or you can get zofran in tablets that dissolve under the tongue. Both are big helps. Otherwise, either get phenergan suppositories or you can crush phenergan and mix with a little butter to make your own suppository. shape it into a little bullet like shape and stick in the freezer for five to ten min and then it works pretty well.
For most of these things stick wth the BRAT diet once they can tolerate a bit of solid food.
B = Banana
R = Rice
A = Applesauce
T - Toast
If you put the applesauce into a popsicle mold or into an ice cube tray that you cover iwth foil or plastic wrap and stick toothpicks or popsicle sticks into, it makes an easy to digest popsicle. It adds some nutrients and is much slower to eat than a dish of applesauce, so it stays down better. I use the all natural unsweetened applesauce and sweeten it just a little because the amt of sugar added at the factory is nuts - WAY more than you would add at home.
