Overnight Blood Sugar Monitoring
Recommended Monitoring Schedule
Newly Diagnosed (First 3-6 months)
- Check blood sugar at bedtime (8-9 PM)
- Middle of night check (2-3 AM)
- Wake-up check (6-7 AM)
- Additional checks if illness or schedule changes
Established Management (6+ months)
- Bedtime check every night
- Middle of night check 2-3 times per week (or as directed)
- Wake-up check every morning
- Increase frequency during illness, growth spurts, or routine changes
When to Check More Frequently
- Illness: Fever, vomiting, diarrhea, or any signs of being unwell
- Schedule changes: Late bedtime, missed meals, or unusual activity levels
- Insulin adjustments: New doses or timing changes
- Growth spurts: Increased appetite or rapid growth
- Teething: Can affect eating patterns and blood sugar
- Travel: Time zone changes or disrupted routines
Continuous Glucose Monitor (CGM) for Infants & Toddlers
Benefits of CGM for Young Children
- Reduced finger sticks: Fewer painful blood sugar checks
- Trend information: See if blood sugar is rising, falling, or stable
- Overnight peace of mind: Alarms for high and low blood sugars
- Better A1C outcomes: More frequent data leads to better management
- Activity insights: See how play, meals, and sleep affect blood sugar
CGM Placement and Protection
Best Placement Sites
- Upper arm: Less accessible to curious hands
- Upper buttocks: Protected by diaper area
- Back of arm: Harder for child to reach
- Avoid: Abdomen (too accessible), areas with pressure
Protection Strategies
- Adhesive patches: Extra security and protection
- Clothing barriers: Onesies, sleepers with covered arms
- Distraction techniques: Keep hands busy with toys
- Positive reinforcement: Praise for leaving CGM alone
CGM Alarm Settings for Sleep
- Low alarm: Set at 80-90 mg/dL for overnight
- High alarm: Set at 200-250 mg/dL (consult your team)
- Urgent low: Always set at 55-60 mg/dL
- Parent/caregiver phone: Ensure alarms wake you up
- Backup alarms: Consider multiple devices for redundancy
Bedtime Routine for T1D Management
Optimal Bedtime Routine
1
Dinner & Evening Snack (6-7 PM)
Consistent timing helps establish routine and insulin effectiveness
2
Bath Time & Quiet Play (7-8 PM)
Calm activities help transition to sleep mode
3
Bedtime Blood Sugar Check (8-8:30 PM)
Target range: 120-180 mg/dL for overnight safety
4
Bedtime Snack if Needed (8:30 PM)
If blood sugar <120 mg/dL, offer 15g carb snack
5
Story Time & Sleep (9 PM)
Consistent sleep time supports healthy circadian rhythms
