How To Watch Your Grandchild With Type 1 Diabetes
Educational only — not medical advice. Always follow the parents' written protocol and your grandchild's diabetes care team's guidance.
For The Parent Forwarding This To Grandma
Hi. I wrote this for my own mom the first time she watched my daughter for a weekend. Forward it to your parents, in-laws, or whoever is watching your T1D kid. The goal isn't to teach them everything — it's to give them confidence on the basics so they're not afraid to babysit.
The most important thing you can do as the parent is leave a one-page written protocol on the fridge: target range, low threshold, low-treatment steps, your phone, partner's phone, endo's after-hours line. Don't trust verbal instructions. Don't trust their memory. One page. Fridge. Done.
For The Grandparent — The Three Things To Know
1. The Target Range. Every kid's number is different, but most kids' "in range" is somewhere between 70 and 180. Below 70 is a low (needs treatment). Above 250 needs a parent text. The exact numbers will be on the page on the fridge.
2. The Low Treatment (Rule of 15). If the CGM beeps low or your grandchild says "I feel low" — give 15g of fast carbs (4 glucose tabs, a small juice box, or 2-3 Smarties rolls). Wait 15 minutes. Re-check. Repeat if still low.
3. The Emergency Numbers. Parent's cell. Partner's cell. Endo's after-hours line. 911 for severe lows where the child won't wake up or can't swallow. All on the fridge sheet.
That's it. Three things. You've got this.
CGM 101 For Grandparents
The CGM (Continuous Glucose Monitor) is the round sticker on your grandchild's arm or stomach. It checks blood sugar every 5 minutes and sends the number to a phone or receiver. You'll hear it beep. The beeps come in two flavors:
- Low alarm (urgent beep, often a siren sound): Blood sugar is below 70 (or whatever threshold the parent set). Action: 15g of fast carbs, wait 15 minutes, recheck.
- High alarm (gentler beep): Blood sugar is above 250 (or threshold). Action: Text the parent. Usually they'll talk you through whether to give a correction dose or just wait.
The CGM also shows an arrow — straight, up, down, double-up, double-down. Down arrows mean BG is falling fast. Up arrows mean BG is rising fast. If the parent says "watch for a down-arrow at 90" — that's a coming low and means start the 15g now, not when the number hits 70.
The Grandparent Emergency Kit
You should have your own kit at your house. Don't depend on the parent to pack everything every visit — that's exhausting for them, and you want this stuff at-hand.
Dex4 Tropical Fruit Glucose Tabs (50 ct)
The "every grandchild low" treatment. 4g of fast carbs per tab — exact dosing. Tropical Fruit is the flavor most kids will take willingly even when they feel rotten. Keep a bottle in your kitchen, your car, and your purse.
Check price on Amazon →Dex4 Liquiblast Liquid Glucose (15g)
The "she's too dizzy to chew" backup. Sippy-style bottle, fast absorption, one bottle = full 15g treatment. Cheap insurance — keep two in the kitchen cabinet.
Check price on Amazon →Smarties Candy Rolls (Bulk Bag)
6g per roll. Cheap, dye-free options available, kids will take them when they refuse glucose tabs. Keep a jar in the kitchen cabinet labeled "LOWS" so you grab the right one without thinking.
Check price on Amazon →BD Home Sharps Container (1.5 qt)
If your grandchild is on insulin pens or syringes, you need an FDA-compliant sharps container at your house. Snap-lock lid, holds hundreds of pen needles. Keep it on a high shelf away from younger grandchildren.
Check price on Amazon →Snack Swaps For The Grandparent Pantry
This is the part where grandparents most often slip up unintentionally. "Just a small cookie" doesn't seem like a big deal — until the unbolused 15g of cookie sends BG to 280 and ruins the afternoon.
The fix isn't "no treats at grandma's." It's stocking known-carb or no-carb versions of the treats your grandkid loves so you can say yes confidently.
SkinnyPop Mini Bags (30-pack)
~7g per mini bag. The "have a snack at grandma's" option that doesn't require you to call the parent for a carb count. Keep a basket on the counter.
Check price on Amazon →Old Wisconsin Pepperoni Snack Sticks (28 ct)
0g carbs. The "free food" snack your grandkid can grab anytime, no parent text required. Keep a bag in the pantry and one in the car for the long drive home.
Check price on Amazon →Jell-O Sugar Free Gelatin Cups, Strawberry
0g carbs. The "dessert at grandma's" without a bolus. When the other grandkids are having ice cream and you want yours to have something cold and sweet too, this is the bridge.
Check price on Amazon →"A Kids Book About Type 1 Diabetes"
The best gift you can buy yourself as a new T1D grandparent. Modern, kid-voiced, written for the diagnosed child but pitched in a way grandparents finally "get it." Many T1D families gift this book to grandparents in the first month.

Grandparents, this is what to ask the parents for before your first solo babysit. They should write it out and tape it to your fridge:
- Target BG range: ___ to ___
- Low threshold: below ___ = give 15g fast carbs
- High threshold to text parent: above ___
- Where insulin lives (fridge / countertop), and where the glucagon emergency kit lives
- Snack rules: what's "free" (no bolus needed) and what needs a dose
- Pre-dosed meal cards for the meals during your visit (parent writes the dose, you administer)
- Parent cell, partner cell, endo's after-hours line, 911
If they haven't given you this — ask. Politely. It's not pushy. It's safety.
When To Call vs When To Handle It
You can handle it (and then text the parent after):
- A low between 55–70, treated with glucose tabs, comes back up in 15 minutes.
- A reading above 250 that drops within an hour after a correction the parent walked you through.
- A sensor that fell off but the parent has a backup with you.
Call the parent immediately:
- A low under 55 that doesn't respond to 15g of fast carbs after 15 minutes.
- A high over 300 with ketones (if you've been trained to check) or signs of nausea/vomiting.
- Any time you're not sure. Always call.
Call 911 immediately:
- The child won't wake up, can't swallow, is seizing, or is unresponsive.
- You can't reach the parent and you're not confident the situation is stable.
911 is the right call when in doubt. Always.

Frequently Asked Questions
What does a grandparent need to know to watch a T1D grandchild?
The three essentials: target blood sugar range and low threshold, how to treat a low (15g fast carbs, wait 15 minutes, recheck), and emergency phone numbers. The parents should leave a written one-page protocol on the fridge. You don't need to memorize insulin dosing — they handle that.
How do you treat a low blood sugar in a child?
The "Rule of 15": give 15g of fast-acting carbs (4 glucose tabs, a 4oz juice box, or 2-3 Smarties rolls), wait 15 minutes, recheck the blood sugar. If still low, repeat. Always confirm the protocol with the child's parents and care team.
What snacks should grandparents have for a T1D grandchild?
Keep a mix of free-food snacks (pepperoni sticks, sugar-free Jell-O, ParmCrisps), known-carb snacks (SkinnyPop mini bags ~7g, single-serve pistachios ~5g), and low-treatment supplies (glucose tabs, Smarties). Stock both at your house so you don't depend on the parent packing for every visit.
