Sorry didn't know where to put this as DD is obviously beyond toddler

DH & I noticed a clicking sound the other day as DD walked past (she's 4&1/2yrs old). I thought it was her ankle but after making her walk back and forth (much to her amusement) we realised it was her hip. She does complain of sore legs every now and then but not often enough for us to be concerned, although if her hip is clicking it kind of makes sense?

I'm not sure which course of action to take - Do I take her to the GP? Pead? Or is it just a growing thing?

TIA
