Metanium? That's what we use, too. Seems to help quite quickly.
G has the bottom from hell at the moment, too. I can't remember when he last had a solid poo. I called the GP to ask if he should come in, but with no other symptoms than runny poo, she said wait it out. After having a very long break from "he must be teething," I think I'm going back to it. It MUST be his teeth!
I'm going to whisper this so as not to anger the sleep gods but, G has been sleeping through for at least 4 nights in a row. I don't know what happened, but he seems to have come out the other side. I hope it lasts! No progress in weaning him but I'm picking my battles and I pick sleep!!
FfFf I can only imagine what it's like for you at the moment. Hope these last days go very quickly and the Bloke is home safe and sound in no time.
Am looking after another 16 month old tomorrow morning. Help me Rhonda!
