Other moms have seen a similar rough sleep patch around age 3, often linked to night terrors, bad dreams, fear of the dark, or shifts in family dynamics. A night light and some patience helped one family get through it.
⚠️ Caution:If night waking is frequent, severe, or you suspect night terrors or another underlying issue, check in with your pediatrician to rule out anything medical and get guidance specific to your child.
Parents in this discussion worried about why a previously settled toddler suddenly stops falling asleep on her own and keeps waking through the night, wondering if something is wrong. The reassurance from another mom is that this can be a normal phase around age 3 - tied to things like night terrors, bad dreams, fear of the dark, or even a change in family dynamics such as a new baby - and that simple steps like a night light helped her family get through it.
Here's what moms in our community shared based on their own experience.
It could be that she is scared of the dark or having night terrors - try a night light. My daughter went through a phase of night terrors and bad dreams around when she turned 3, and a separate phase of not sleeping well at age 3. In our case we had a new baby around the same time, so part of it may have been a shift in family dynamics rather than the age itself.
