Is she having solids? and if so, is she eating a meal at night and what type of food? We had LOADS of sleep issues that we first thought was teething, but it just seemed relentless and giving panadol didn't seem to make a whole lot of difference. And when he was asleep it wasn't a *good* sleep either kwim? When he was nearly 9mths, we had a gastro bug go through us all and I was just too sick one night to make him dinner, so he went without solids that night and guess what? he slept for 10 HOURS!!!!! I didn't give him solids again the next night because I was still ill and we got another solid nights sleep! Literally overnight all our sleep issues stopped - even when he did cut other teeth it was nothing compared to what he was doing. He did have reflux issues, so the solids were just making that worse and his gut just couldn't digest it properly at night. Around the same time I also read and article in Practical Parenting magazine about babies sleep and the correlation with high GI foods. If your baby has a diet of high GI foods, it can interfere with their sleep. So when we started to re-introduce an evening meal, we started with low GI foods only and we had no sleep issues. We also realised that potato gives him belly aches and even now he can't eat potato at night.

Maybe something to think about anyway.
