Ds is 4 months old and I've noticed my dm will never call me 'mummy' when speaking to him. You know how you might say Where is mummy going?' etc, she says 'Where is mum?' And tries to teach him the word 'mum mum mum'.
I know that seems like nothing but it annoys me because I thought most people say 'mummy' when speaking to a baby or young child.
Then a few days ago I heard her teaching him my first name. Also i have heard her call to herself as mummy (like 'come with mummy') a couple of times but I put that down to a slip of the tongue as most of the time she says grandma. However, since hearing her trying to teach ds to call me by first name I'm starting to get concerned.
