Just a follow up, in case anyone else has a similar problem.
Frequency of the poos has decreased a bit, but they are still as "firm" as ever. Doesn't appear to be bothering her. Dr said if she is ok, i.e. not crying or uncomfortable, not to worry. Some kids are just like that.
That said .. it's funny how different the kids are. At the same age, DD1 was eating whole bananas for breakfast and was still doing mushy poos. Now my girl's cousin is apparently the same as DD2, poos frequenly and firmly. So it's amazing how everyone's body processes things differently!
(On the plus side of all this, whilst there can be several poos a day to clean up, they are not messy in the least!)
