Part 2: Accepting Imperfection

What you'll learn

Understand why perfect blood sugar control is physiologically impossible
Know the ADA's recommended time-in-range target for children with T1D (>70%)
Identify factors outside your control that affect blood sugar
Reframe success away from perfect numbers and toward your child's overall wellbeing

The Truth Every Experienced Parent Eventually Learns

Here it is: perfect blood sugar doesn't exist. Not for your child, not for anyone with T1D. Not even with the most sophisticated pump, the most accurate CGM, the most diligent carb counting, or the most dedicated parents.

This is not a flaw in your management. It is the nature of the disease. And once you accept it — truly accept it — a significant weight lifts.

Why Perfect Control Is a Myth

The same meal can produce wildly different blood sugar results on different days. Why? Because blood sugar is affected by far more than just food and insulin:

Factor	Effect on Blood Sugar	What You Can Do
Stress and emotions	Releases cortisol → raises BG	Recognize, don't over-correct
Illness	Usually raises BG; sometimes drops	Increase monitoring; follow sick day protocol
Exercise	Can raise or lower BG depending on type and intensity	Check before/during/after; carry fast-acting sugar
Growth spurts	Often raises insulin needs significantly	Pattern recognition; contact team for adjustments
Hormones	Major impact, especially in adolescence	Predictable patterns; adjust with team
Sleep quality	Poor sleep raises BG	Good sleep hygiene; adjust if consistent pattern
Weather	Heat can increase insulin absorption; cold can slow it	Awareness; don't over-react to single readings
Injection site	Scar tissue slows absorption	Rotate sites consistently

Even insulin pumps and continuous glucose monitors — the most advanced T1D technology available — cannot perfectly replicate a working pancreas. A healthy pancreas responds to blood sugar changes within seconds. No technology is that fast.

Scenario: David's Obsession

David, father of 9-year-old Léa, spent three months glued to his phone, checking her CGM app every 10 minutes. If her blood sugar went above 160 mg/dL, he'd panic. If it dipped below 90, he'd rush to her room with juice.

At their quarterly appointment, his endocrinologist gently told him: "Léa's time in range is 72%. That is excellent. You are doing a wonderful job. But I'm worried about you."

David started working with the team's psychologist and learned to check the CGM three times a day instead of every 10 minutes. The numbers didn't change. His anxiety did.

What the ADA Actually Recommends

The American Diabetes Association's recommendation for children with T1D is:

Time in range (70-180 mg/dL): more than 70%
Time above range (<180 mg/dL): less than 25%
Time below range (<70 mg/dL): less than 4%

That means: being in range 70% of the time is the goal — not the minimum. Many families take months or years to reach it consistently.

Info

A wise endocrinologist once said: "If your child is growing well, going to school, playing with friends, and mostly happy — you are doing an excellent job, regardless of what the numbers say."

What "Good Enough" Looks Like in Practice

Instead of chasing perfect numbers, aim for:

Time in range above 70% — measured weekly, not daily
Catching and treating lows quickly — response time matters more than preventing every single low
Avoiding prolonged highs — brief spikes are normal; hours above 300 mg/dL need attention
Your child thriving — going to school, playing, laughing, growing. This is the real measure

Tip

Look at CGM data weekly, not hourly. Daily fluctuations are noise. Weekly trends are signal. Your endocrinologist will review the data with you at each appointment and help you identify patterns that actually matter.

Key takeaways

Perfect blood sugar is physiologically impossible — the same meal produces different results on different days
Stress, illness, exercise, growth, hormones, weather, and injection sites all affect blood sugar outside your control
The ADA target for children is >70% time in range — not 100%, and it takes time to achieve
"Good enough" means TIR >70%, catching lows quickly, avoiding prolonged highs, and a thriving child
Review CGM data weekly for trends, not hourly for reassurance
