My DS is quite a clicky little man, he has had all the newborn checks with a paed which were all fine. At the moment his ankles click the most which I have read that this can be caused by walking on tiptoes which he does all the time. It doesn't happen too often tho maybe once every couple of weeks. I am a super clicky person too, all the time so perhaps he is just going to be like me. He never flinches or indicates pain when it happens so my mothers intuition has always told me not to be too concerned. But I keep a close eye on him and will likely mention it when we visit a doc again. Like you I have googled it too and although I haven't found a great deal of info what I have found has said it isn't anything serious. Oh and I hear DS's clicking too but it ie soft more like a little pop compared to my adult body clicks.
