Thanks All.
I have bought Bonjela and giving her regular Panadol to help ease the pain. Her sleep has started to settle back to normal even though she has now adopted a sleep at 8.30pm and wake at 9.30pm and be awake til midnight stint! I hope to break that cycle in the next few nights (fingers crossed). She is only putting her fingers to one side of her mouth, so i'm guessing another teeth is to arrive on that side. She has 3 in total, so #4 will pop out soon!
Thanks for all your advice.
