Ladies, thank you all so much for your replies.

Kazbah - I did think of that, but the heater is always on, so I don't think the air is getting cold. I do have asthma, so that has been playing on my mind a bit.

Olive - I really hope so too. She had an explosive poo for the first time in ages yesterday. Was so gross! I didn't know there was anything she could take, so thanks for the tip.

Kaz - Wow, our stories are so similar. I hope your DS is feeling better soon.

So last night, DD didn't throw up. I was on egg shells all night just waiting for it to happen, and it never did. We have a Drs appointment tomorrow, so hopefully we'll shed some more light on the situation then. But for now, we have another vomit free night.

Thanks again ladies
