What age did your dcs switch from 'Mummy' to 'Mum'?

[Stormfly]

Just wondered on the average age for this. Ds has noticed that most others his age say 'Mum' now and requested that I ask on Mumsnet. I have told him he can call me whatever he likes (within reason!).

Mine started aged 3 . I still get mummy sometimes but it's usually MMMUUUUUMMMMYYYY ifyswim.

My Ds is nearly 9 and still calls me Mummy. When were around his friends he tries to call me Mum but finds it hard to keep it up!

Can't remember. I think they ran together from first speech. They still use both depending on circumstances and they are 8 and 13. I don't understand people like my sil who won't answer to Mum until her children reach a certain age....

Started about the same time they went to school (still get mummy when they're ill or want something though!)

DD has just turned 7y and still calls me mummy and DH daddy. Hopefully for a whie longer

My 17 year old calls me mummy

my kids still do it aged 16 & 19....admittedly they are asking for money

My DS1 is 2.9 and has just been through a phase of calling me 'mum' - I assume he picked it up at nursery Although he did call me 'mamma mia' the other day and I have absolutely no idea where that came from - I can't imagine that they have conversations about Abba songs/films at nursery

Anyway, thankfully he is back to mummy now!

my DS is 3 and ive been, mammy, mum and currently mamma.

DS1 was about 5 when he started calling us mum and dad, but DS2 was only 2.5. He is nearly 6 now and it still makes me chuckle when I hear it - too grownup
