I have a 13m old. Been talking and practicing words from 10m, has quite a few words now but one thing I cannot get lo to say is mum mumma mummy mumumum I have also noticed lo can say daddy but chooses to use daddy's actual name which lo can also say. Has started to say a few names. But never mum. What is going on here?? My others would say mum mummy etc.
(The words are not perfect but we can understand)
