Thanks kristinmc. Definitely things to bear in mind! My HV said follow on shouldn't be necessary if she is having meat at fish so I shall stay with 1st and see how she goes!
Maybe I might try 1/2 and 1.2 like you are doing? She does tend to stir about 4/5am and I have to go and settle her back to sleep! It would be lovely for her to go to 7 maybe! I might be asking too much though! She is already on 3 meals a day
