Pre-Bolusing for a Picky Toddler with Type 1 Diabetes | Combo Bolus
Your toddler asked for the macaroni, then looked at it like you served packing peanuts and demanded the one other food in the house, and you've got insulin on board for a meal that just got canceled. This episode is for the parents dosing...
The episode, word for word
Your toddler asked for the macaroni. Specifically. Looked you dead in the eye and said the word "macaroni" like a tiny mob boss placing an order. So you made the macaroni. You dosed for the macaroni.
And now your toddler is staring at the macaroni like you served them a bowl of wet packing peanuts, pushing it to the far edge of the table, and demanding the one other food in the house. And you've got insulin on board for a meal that has just been, without warning, canceled.
Parents, this one's for you. The tiny food critic.
I'm Neil Greathouse, this is Your Best T1D Year, and I have a ton of parents in this audience, so let's get practical and a little ridiculous, because that's parenting.
The whole pre-bolus thing assumes you know how much is getting eaten. And with a little kid, you know nothing. You know less than nothing. You are dosing into pure chaos. A toddler's appetite has more mood swings than a crypto chart in a bad week. One night they eat like a tiny linebacker carb-loading for the big game, the next night a single grape is "too spicy" and they need to lie down about it. And meanwhile you're doing insulin math against a moving, screaming, devastatingly cute target. You would trade a year off your life for the calm of one single Bluey episode, and instead you're running carb calculations against a person who just discovered the word "no" and is taking it for a test drive.
So here's the playbook, and I'm pulling this straight from what the actual pediatric diabetes guidelines say, because this is one of those spots where the rules are way gentler than parents think. Specifically, the international guidelines, ISPAD, that's the group that writes the rulebook for kids with type 1, recommend a combo or dual-wave bolus for uncertain eaters. You give part of the dose before the meal, then drip the rest in over the next 20 to 40 minutes once you see what actually got eaten. And there's genuinely good news in the research here. A systematic review in kids found that pre-meal dosing, when you CAN pull it off, lowered the after-meal glucose peak and even lowered A1C over time, with no increase in lows. So "before" is still the goal when it's safe. The guidelines just hand you a real, written exception for when it isn't.
Idea one, the split. Instead of dosing for the whole plate up front and lighting a prayer candle, you give insulin for the part you're confident they'll eat, and then you give the rest after, once you've seen what actually went down the hatch. On a pump there's often a combo or extended bolus that makes this smooth. Off a pump, it's just a smaller dose now, a top-up later. You're dosing for the food that's actually inside the kid, not the food staging a standoff on the plate.
Idea two, with little kids, you're allowed to dose during or even after the meal. We'll go deep on that Friday, because I think a whole lot of you are carrying guilt you do not need to carry.
Idea three, keep fast carbs right there on the table. Always. If you did pre-bolus and the kid stages a hunger strike worthy of a documentary, you've got juice ready to catch the drop. Net first, then the tightrope. Same as the grown-ups.
And listen, I know your kid is currently saying things like "skibidi" and "that's so six-seven" and calling things "bussin" and a bunch of other words that sound like a Roomba achieving consciousness. I do not understand a single one of them. I have nodded along to my own family like I'm fluent. But I do understand a parent doing insulin math at 6pm while a small person renegotiates the entire dinner contract in a language from the future. That part, I get completely.
Your challenge this week, parents. Try the split on one unpredictable meal. Dose for what you're sure they'll eat, top up after. Notice how much less terrifying that is than betting the whole dose on a toddler's mood holding steady for nine minutes.

You're not doing a bad job. You're doing a difficult job, for someone who cannot yet appreciate it and just called their pasta "spicy" for absolutely no reason. One day they'll understand what you did for them. Today, I've got you.
I'm Neil. Friday, the permission slip every T1D parent needs. See you then.
