Advice please 
My little one has just turned 9 months and still has no teeth. She has been sleeping through the night for the last couple of months, all of a sudden the last few nights she has been waking 2/3 times and screaming for a long time before I can calm her down. I have never heard her cry like this. When I looked in her mouth there is no sign of any bottom teeth but you can clearly see 3 top teeth in the gum (two front teeth and a thang) but they are not cutting through the gum, she's not dribbling loads and the gums don't look swollen. She does keep hitting her face/mouth.
Could this be teething? There is no other obvious reason for her to be waking up so upset 
Thanks! X
