My son is going through growing pains (which I believe him about, as I remember them and they chuffing hurt!), but I have been checking the archives and other posters have said it happens between 5 and 9 as a rule. I remember mine at 7-8 years old and also the frustration that my parents didn't believe me, which I also see is common from the archive threads. DS is only 3, but a big lad for his age, and I wondered if anyone else has a preschooler with the same issues? I am trying calpol and massage atm - does anyone have any better ideas?
