It’s not just a pump. It’s a life-changer.

Help kids as young as 6 take an active role in managing their diabetes.

Smart device. Smart conversations.

Kids want a say when it comes to choosing how to manage their diabetes. We’ve made that choice easier for them and their parents by designing a system that helps to keep diabetes under control. Here are a few things to talk about when having a conversation about getting started on the t:slim X2™ insulin pump with Control-IQ® technology.


The t:slim X2 pump is the easy choice

The t:slim X2 insulin pump with Control-IQ technology offers more freedom for kids and greater peace of mind for their parents.


Doodle Sports

Flexibility to Connect / Disconnect

It’s easy to temporarily disconnect the pump from an infusion set for showering or sports. Using data from Dexcom G6 continuous glucose monitoring (CGM), kids can quickly see where they’re trending, and reconnect in a snap.

A Predictive Algorithm

Control-IQ technology predicts glucose levels 30 minutes in advance and automates insulin delivery. It’s been shown to increase time in range,* which means more time to just be a kid, and greater peace of mind for parents.


Doodle Sleep

Rest Easier

Control-IQ technology on the t:slim X2 insulin pump is designed to help reduce the need to wake up at night to check numbers and have to correct a low, helping improve everyone’s nights and mornings.


Doodle Super Kid

Customize Profiles

Programmable profiles, as well as optional settings for Sleep and Exercise Activities, let kids be kids. Plus, the t:slim X2 insulin pump fits easily into a small pocket or pouch to keep up with kids on the move.

The Comfort of Control

Managing diabetes can feel like your brain is working overtime. Relax knowing that our insulin delivery system includes automatic correction boluses when needed, to help kids better control their diabetes from day one.

"CGM definitely makes you feel a lot more secure and a lot more safe. Now that I have it, I can’t imagine life without it.”

Sofia, diagnosed 2015



"Tandem has made a difference not just in my life, but my family’s life. My mom used to come to school to give me insulin. Now with a Tandem pump, I can do it myself.”

Jillian, diagnosed 2011



“I was able to stay in class much longer than I normally would have been because my Dexcom was working with my t:slim X2 pump.”

Chris, diagnosed 2008

Responsible Use of Control‑IQ Technology

Even with advanced systems such as the t:slim X2 insulin pump with Control-IQ technology, you are still responsible for actively managing your diabetes. Control-IQ technology does not prevent all high and low blood glucose events. The system is designed to help reduce glucose variability, but it requires your accurate input of information, such as meals and periods of sleep or exercise. Control-IQ technology will not function as intended unless you use all system components, including your CGM, infusion sets and pump cartridges, as instructed. Importantly, the system cannot adjust your insulin dosing if the pump is not receiving CGM readings. Since there are situations and emergencies that the system may not be capable of identifying or addressing, always pay attention to your symptoms and treat according to your healthcare provider’s recommendations.


*As measured by CGM (70-180 mg/dL).
†Users must still bolus for meals and actively manage their diabetes. If glucose values are predicted to be above 180 mg/dL, Control-IQ technology calculates a correction bolus using the Personal Profile settings and a target of 110 mg/dL and delivers 60% of that value. An Automatic Correction Bolus will not occur within 60 minutes of a bolus that has been delivered or cancelled.
‡If your glucose alerts and readings from the Dexcom G6 do not match symptoms or expectations, use a blood glucose meter to make diabetes treatment decisions.
