Is it strange for a 4 year old to be wearing diapers?

No, it is not necessarily strange for a 4-year-old to be wearing diapers. Diaper training is a developmental milestone that children reach at different ages, and there is no one-size-fits-all approach. Some children may be fully potty-trained by age 4, while others may still be in the process of learning. There is no right or wrong answer, and each child will progress at their own pace.

If you are concerned about your child's progress with potty training, talk to your doctor or a child development specialist. They can help you assess your child's readiness and provide guidance and support.
