I had this a lot with dc1, mw looked at me like this when I asked her about it. It happened a few times with dc2 too, I have no idea what it was but I've read a few threads on here about it so it can't be that uncommon! Fwiw I had 2 straightforward pregnancies and healthy babies.
Yes! It's very common apparently (loads of conversations on here about it) but there seems to be no definitive explanation. My MW had no idea. I do find it odd that 1st pregnancy had none of this but 2nd has been constant popping and clicking! Would love to know what it is!
I had this with DD2. I was worried I might have broken her! But the radiographer assured me that as you can't break a matchstick in a bag of water(!!) as its protected by the fluid, you can't break baby's bones. I'm quite a clicky joints person and I noticed in the first couple of months after she was born that she too had clicky shoulders. GP was not worried and it's disappeared now. HTH!
