Sick Day Muffins

We're sick around here.  It's Paul's fault, really.
No, not really.
But Paul was the first one to have sinus stuffiness.  Then Nathan got sick Friday afternoon, and has pretty much not moved off the couch since then.  Fever of 103.  Jacob came down with it on Sunday (we stayed home from church - for once they were sick on a day convenient for me to skip!).  I'm trying to get sick, but I am hitting the Zicam pretty hard.  I can't get a cold this week!  (Our worship night is this Sunday.)
Nathan has me concerned.... The high fever, complete lack of appetite, and the just laying around all the time.  I can't get him interested in doing anything, and then he acts like he can't concentrate if I do get him to try to attempt something.  I keep going back and forth whether to take him to the doctor.  First off, it's $20 just to walk in the door.  We don't really have that right now.  And if it's just a virus (which I'm pretty sure it is since we've all got it in some form), the doctor will send us back home with a "just keep an eye on him."  So $20 wasted.  Plus, there's the chance that we'll pick up some other vile disease while we're there - which has happened before, more than once.
I was really hoping that today is the turnaround day.  So I thought I'd tempt them with something tasty to eat.  It worked, sort of.
These muffins were a variation of a Better Homes and Gardens cookbook recipe.  The first time I made them like this (last week), Paul ate 5, Nathan ate 3, and Jacob ate 2.  Then the boys both wanted another for their mid-morning snack.
So I tried them again.

3/4 cup white flour
3/4 cup wheat flour
1/4 c(ish) oatmeal
2 tsp baking powder
1/2 tsp salt
1 tsp(ish) cinnamon
1 beaten egg
3/4 c milk
1/4 c oil

Mix dry ingredients.  Stir together egg, milk, oil and pour into dry ingredients.  (May need to add more water or milk to get it to right consistency - not as thin as cake batter, but not so thick it clumps up in the whisk.)
Divide among 12 muffin cups.
Top with streusel:

1/4 c (half stick) butter
1/3 c flour
1/3 c brown sugar
1/2 tsp(ish) cinnamon

Combine flour, brown sugar, cinnamon.  Cut butter in using a pastry knife.  Sprinkle by the tablespoon full over the unbaked muffins.

Bake at 350 for 14-15 minutes.
*(ish) means I didn't actually measure it.  Just a guesstimate.

Nathan actually asked for one.  He ate the streusel top off of it, and left the bottom half.  Jacob ate one for breakfast, then wanted another for lunch.  When they're sick, I'm like whatever.  As long as they'll actually eat - it may not have lots of nutrition, but it has calories, which is energy to fight illness..... right?  Nathan's pretty much just ate Cheetos and cookies for the last 4 days.  I'm just happy he'll eat that much.
So we'll see if today is the turnaround day.  Nathan voluntarily went to take a nap at 11.  But so far, no fever.......
