Sleep regression is a common issue that many parents face with their infants and toddlers. It can be frustrating and exhausting, especially if it seems like there is no apparent reason for the disrupted sleep. However, there are several common causes of sleep regression that parents should be aware of. These can include developmental milestones, teething, illness, changes in routine or environment, overstimulation, and even separation anxiety. By understanding the underlying causes of sleep regression, parents can take steps to help their children get the restful sleep they need. This may involve making adjustments to their routine, providing comfort and reassurance, or seeking medical advice if necessary. Ultimately, addressing the root causes of sleep regression is essential for promoting healthy sleep habits and ensuring that both parents and children can get the rest they need to thrive.
