My little 3 1/2 year old girl is complaining of pain in her bottom. She has had this for the last 3 nights (it does not appear to happen during the day).  She tries to do a poo but is unable to do so and usually falls asleep around midnight but I think it is because she is exhausted.  She has also been going to the toilet a lot during the day as well mainly weeing.  Can you suggest any cause?
Dear parent, I understand your concerns, but it seems that your child is suffering from constipation. You should give a lactulose syrup 3 times daily. Make sure your child is adequately HY Chat Doctor.  One of them should be orange juice as decreased intake of fluids leads to constipation.
