Our baby has suddenly started having very creaky / cracky joints, it is so weird! It doesn't seem to bother him. I had a quick look on the net and it seems to be not abnormal but still a bit freaky! Any one else had it and how long did it last?
Both my boys dud this @clothmama. I think it was when they had grown and their bones were slightly too big/small for the gaps etc. Once everything had caught up, they were fine.
I would just keep an eye on it and if it doesn't sort it self out, get him checked over.
