Just curious.
DS1 is nearly 6, and some of his friends say "Mum" while some still say "Mummy". I'm still Mummy, and I have to confess I prefer it. Clinging to the early years I suppose!
So I was wondering, what age to children tend to switch? I imagine it makes a difference if there are older siblings around. No doubt DS2 will call me Mum as soon as DS1 does.
