Sleep and Advice

Hi

I have a 18 month old daughter who still, unfortunately has reflux and will/cannot sleep though the night. She is still sleeping in our bedroom and gets into our bed every night, after she has been asleep for only 3 hours. She then wakes up about another 3 times. I know her reflux is aggravated by teething, and she is teething at the moment but I would be grateful if anyone could give me some advice.
I should have returned to work 6 months ago, even though I really do not want too, anyway I don't have the energy!
