Toddlers may show signs of regression in behaviour or emotion – wanting a bottle or a nappy when you bring your new baby home, for instance, without any cause for concern. However, if your child’s physical development or motor skills show any signs of regressing, then there is definitely a serious medical problem, and you need to seek immediate medical advice.
Losing any physical ability or skill that has been mastered is one of the few concrete warning signs that there is trouble that your child can display, and it should never be ignored. This kind of regression is linked to many serious conditions, including cancer, encephalitis, brain tumours, epilepsy, or neurological disorders.
If you notice that your child has regressed in any way, in terms of ability, make an appointment with your doctor immediately. You will want to have tests done, and find the problem as soon as you can – since many of the underlying disorders are life threatening.
