frequent urination in 4 yr old ds

[greedygreedyguzzler]

my ds has recently, over the past week or so, started weeing all the time! its never very much, so i am not overly concerned about diabetes, but he keeps saying he needs to go every 10 to 15 mins.
i have researched it on the internet and it looks like one of th causes of this can be some kind of emotional upset but i honestly cant think of any reason why he should be upset about anything.
his behaviour has also been shocking this past week and normally he is a little angel.

anyone else experienced this?

he could have an infection- does he complain of stinging/ pain when he wees?

i would take him along to the GP just in case- don't tell the GP you researched it on the internet, though- it's the bane of their lives!
