Baby Night Crying Guide: From Colic to Sleep Regression Solutions
Are you exhausted from your baby crying at night for no apparent reason? Night crying (colic) is one of the most challenging experiences for parents. According to the American Academy of Pediatrics(AAP), colic typically starts around 3 weeks, peaks at 6 weeks, and improves by 3-4 months. Here's everything you need to know about causes, solutions, and when to see a doctor.
What is Colic?
AAP Definition
The American Academy of Pediatrics(AAP) defines colic as:
💡 Colic = Crying for 3+ hours a day, 3+ days a week, for 3+ weeks, that is difficult to sootheTimeline
| Age | Symptoms |
|---|---|
| 2-3 weeks | Onset |
| 4-6 weeks | Peak (worst) |
| After 6 weeks | Gradual improvement |
| 3-4 months | Most cases resolve |

2. Accumulated Fatigue

- Overtired babies struggle to fall asleep
3. Sleep Regression
- Occurs during developmental periods (4 months, 8 months, etc.)
- Temporary phenomenon due to brain development
Medical Causes (Rare but Check)

| 2 | Side/Stomach | Hold on side or tummy (always sleep on back!) |
| 3 | Shush | Make "shh" sounds near ear |
| 4 | Swing | Small, quick movements |
| 5 | Suck | Pacifier or finger |
