to think it's inapproriate to babytalk to your work colleagues?

[MARGOsBeenPlayingWithMyNooNoo]

I don't actually think I am.

Becasue you don't start off a request with "pweeze, pweeze could you get me some etc etc...?" when you're addressing your colleagues.

I don't think it's endearing. I think it's demeaning for both me and for her.

I wouldn't even speak like this to my dcs/dog.

lol. someone I work with (a lovely woman) says 'likkle' instead of 'little' all the time. very annoying!

Clearly she thinks she's cute.

She's wrong.

Ah yes, but she doesn't even have children.

Have you considered sticking one hand on your hip, raising one eyebrow and saying "pweeze?"

and..and she has no respect for personal space.

Maybe she's a 3 yo living in the body of a 23 year old

I considered sending her to the naughty step until she started speaking properly

AAAAAAAARRRRRRRRGGGGGHHH!
I hate this, my sil does this even way before they had children I can't stand it.

When she first met ds she was all "Hewo iccle man, my name is PITA SIL whatsh yaw name den"
He just looked at her witheringly and said "DS and I'm not little I'm 3 actually".

lol at the sarcastic kid

lol

Perhaps she just likes a little roleplay?

I suggest you adopt the role of sulky teenager and fold arms, flop your hair over your eyes and grunt.

That or........
A fun game you may like to try is the 'pitch game'. Answer in kind but a tiny bit higher pitched, see if you can't get her to get her really excited and only annoy dogs.

Slur - I'd love the role of sulky teenager at work.

But just think of the benefits - you could probably get her to do all of your work if you introduce a reward/star chart!
