Yes, babies tend to sleep more after vaccines. Studies show an increase in sleep duration following immunization.
According to research, infants slept an average of 69 minutes more (95% confidence interval: 32–105 minutes) in the 24-hour period after immunization than in the 24-hour period before immunization. Most of this additional sleep was active sleep, with only a slight increase in quiet sleep time.
Here's a summary of the findings:
| Sleep Parameter | Change After Immunization |
|---|---|
| Average Sleep Increase | 69 minutes |
| Type of Sleep | Primarily active sleep |
It's important to note that while an increase in sleep is observed, individual experiences may vary.
