Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.
Get emergency help if your child is difficult to wake, confused, breathing deeply or rapidly, repeatedly vomiting, or severely dehydrated.
This combination can occur with a serious complication of diabetes or another acute illness.
Seek same-day medical advice if new bedwetting occurs with extreme thirst, frequent daytime urination, weight loss, unusual tiredness, or blurred vision.
These can be symptoms of diabetes and need prompt testing.
Your child also needs same-day care for painful urination with fever, vomiting, back or side pain, blood in the urine, or appearing noticeably unwell.
Arrange a routine appointment if bedwetting continues after age 5 and concerns your child or family.
It is also worth discussing if it returns after at least six dry months, or if there are daytime leaks, constipation, an unusual urine stream, persistent snoring, or repeated urinary infections.
Every sign above is quoted from the sofidex article on Bedwetting in children. If you are not sure, err upward — it is always reasonable to be checked.
