For the last few months my son (will be 3 in September) has been complaining of foot pain, mainly at night. He says they hurt and to rub them better. I got his feet measured and made sure he has some supportive clarks shoes. However last night, he woke after a couple of hours hysterical rubbing his legs saying they hurt. With some calpol, rubbing and sleeping in mummys bed 
he settled.
I am sure that is all it is and I do remember growing pains myself, but worry he's a bit too young to experience this. Has anyone else had children with the same and anything that helps?
Thanks
