Thanks for your reply Joanna,

We went to see Mum's speech therapist at the hospital today and mentioned the fat tongue and it's problems to her. The speech therapist was very reasuring and told us that it is quite normal. She had a look at Mum's tongue. There are a few stitches, which still haven't disolved but otherwise it appears to be healing well. The speech therapist said that she will work with Mum to help her get used to her new tongue. She said it is normal that Mum's tongue should feel odd at the moment but in time Mum will get used to it and the movement of her tongue won't be as restricted as it is now.
