Is it okay for a preschooler to wet his pants once in a while?

Daytime wetting, as it's referred to, occurs in about 3 1/2 percent of healthy children (kidshealth.org.nz), and that's on a regular basis. I'd say it's not too unheard of to say that occasionally it might happen in a preschooler once in a blue moon. 2/3 of kids who experience daytime wetting are also bedwetters. So if your child is regularly bedwetting, then there is reason to worry and possibly consult a medical professional. In any case, if problems persist, the following symptoms could be causing your child's daytime wetting problems: a twitchy or "overactive" bladder which may lead to wet pants or urgency a weak outlet valve which may lead to wet pants when laughing, coughing or straining urinary tract infections constipation which can lead to wet pants as well as soiling structural abnormalities with the bladder or the tubes from the kidneys suspicious symptoms include pain on passing urine, a poor urinary stream or continuous dribbling of urine problems with the nerves from the lower spinal cord; weakness in the legs may be associated To clarify, I don't think that a child who has wet himself/herself only a few times is experiencing anything severe.
