It is too short for her to chew on but is still long enough not to choke her. She doesn't even know it is there really.
I peronally do not leave it on overnight but I do know women who do, I am not willing to take the chance.

I prefer natural remedies if possible but in saying that if she needs medication I am happy to give it to her. I personally do not find panadol very effective and a cuddle seems to be alot more satisfiying for her , she is a very calm girl.

Good luck with your scan tonight, I have mine at 2pm this afternoon, I already know that I am having another girl though as I had a CVS at 13 weeks.
I guess I will see your results in our belly buddies thread, I need to head in there and update everyone, I have been a little lazy this week.
