We had to fetch the younger Free-Ride offspring from school yesterday midday on account of an unscheduled bout of vomiting.* Because, you know, the microbes and immune systems tend not to take account of things like our work schedules. ("Or whether we have a science test," the younger Free-Ride offspring chimes in.)
Anyway, since experience has established me as the puke-parent** in the Free-Ride household (the one upon whom a child will vomit in instances where someone is vomited upon), I now have something of a procedure when I get home with a pukey kid. We cover the head of the bed, the pillow, and the floor area adjacent to the child's bed with towels (since, in case of puke, it's easier to remove and replace a towel or two than to strip the whole bed and change the sheets). We provide a nice big aluminum bowl next to the bed ... just in case.
And we don't even think about putting food into that tummy until the tummy shows no signs of erupting.
But then, what to put in the tummy -- what counts as a "gentle" food for a kid recovering from a stomach bug -- is a source of some controversy at Casa Free-Ride.
In the household in which I grew up, flat ginger ale and saltines were the canonical first foods after an upchuck. If they stayed down, maybe 24 hours later you'd get to try some baked custard, the eventually "real" food.
Sadly, we hardly ever have ginger ale in the house, and the Free-Ride offspring have declared saltines strange and disgusting. What this means is that I don't have a well-established safe food with which to test tummy stability.
Indeed, as I was laying down towels, right before I was going to make a batch of baked custard, the younger Free-Ride offspring mentioned that a teacher at the after school program had said that eggs (an ingredient of baked custard) are not a good food for your tummy after vomiting.
This suggests to us that what people consider as the right kind of food to give a kid who's been throwing up must be pretty strongly shaped by what kind of food they were given as kids trying to get better from crummy tummies. Also, it suggests that there is no clear unified theory of the optimal macronutrient composition for these foods -- at least not one upon which a clear majority of grown-ups taking care of these kids agree.
My strategy, drawn from my childhood, has been: fluids with a little flavor (because water tastes funny when you're sick), then carbohydrates with negligible fiber (the dreaded saltines), then some not-too-wobbly protein, and none of it very far from a flavor range it would be fair to describe as "bland". Probably a banana somewhere in there, too.
But, see, now the younger Free-Ride offspring and I are wondering if this strategy is bunkum.***
So, because the younger Free-Ride offspring tells me that a PubMed search would not be a relaxing way to spend a sick day, we're appealing to those more likely to have an actual evidence base here (Pal? Pascale? Other medical/nutrition types?) to tell us whether there is any informed-by-science consensus on what a kid ought to be fed (and in what sequence) once the puking subsides.
* No, we don't have scheduled vomiting. It's just that these stomach bugs hardly ever happen on a day when we had nothing else to do.
** The companion role to "puke-parent" is "poop-parent". My better-half assumed that role, but hasn't gotten any action in it since the sprogs were in diapers.
*** My current favorite alternate theory on why to eat bland foods in the wake of a stomach-bug: You don't want to eat foods with more interesting flavors and textures, especially foods you really like, and then throw them up (if you've tested the tummy too soon) lest you develop a long-lasting aversion to those foods. It took me maybe a decade to get over my aversion to spaghetti and other long pastas served with tomato-based sauces ... because of a stomach flu when I was about 11. On the other hand, if you develop an aversion to saltines, it doesn't really impact your quality of life in quite the same way.
