Nanny calling herself mummy

[PerplexedMummy]

Hi everyone,
I'm looking for some advice from fellow mums as I'm really torn and not sure how to handle this situation.
I have a 7-month-old baby and recently hired a nanny to help a few days a week. She’s warm and seems to genuinely enjoy being around my baby, but she has very limited experience with children under 1 year old — and it’s starting to show.
She struggles with basic care (e.g., recently took my baby out in the sun without a hat, and when my daughter got hot and flustered, she told me she might be "allergic to the sun" 😕). I also worry about how confidently she handles feeding and developmental milestones — it feels like she’s just unaware of what’s appropriate at this stage.
But the thing that’s really bothering me is that she’s called herself “mummy” to my baby several times — saying things like “Mummy’s here!” or “Come to mummy!” when talking to her. I find this incredibly uncomfortable. I’ve tried to brush it off, but it keeps happening, and now I’m not sure if I should have a proper conversation about it or whether this is somehow common and I’m overreacting?
Has anyone else experienced this?
How would you handle it?
Thank you so much in advance — any thoughts would really help.

She sounds more like a teenage babysitter than a nanny, but I'd expect even a teenager to think of putting a hat on a baby in the sun.

She could have read up on developmental milestones in a day if she was bothered.

Well I’m not a mum but I did pretty much raise my younger sibling from baby upwards and a chat isn’t going to fix this. Just get a new nanny. I assume they’re meant to come ready trained!

She should have been gone yesterday...

This can’t be real. This reads like AI has written it.

You need a new nanny.

It's all very "The Hand That Rocks The Cradle" isn't it?

Is she actually qualified as a Nanny? It does sounds as though she bought her certificate on EBay.

Why on earth did you hire such an inexperienced and incompetent person to look after your child???????

Calling herself Mummy is the very least of your concern - or should be!

Is she qualified, where did you find her?

Hell no, you need to remove her ASAP.

Exactly. Why is she still employed by you?

Thank you so much to everyone who took the time to reply — I really appreciate all the advice and different perspectives.
As a first-time mum, I’m also learning on the job, and I didn’t realise just how important it is to have someone who really understands things like weaning and supporting key developmental stages. I guess I assumed a lot of it would be common sense — like making sure a baby has a hat on in the sun, or gently waking her if she’s napped for over 3 hours in the morning (especially after a good night’s sleep and having missed a bottle), knowing that it can throw off her night sleep.
I’ve been feeling really guilty about the idea of letting her go, especially as my daughter does seem to love her — which I suppose is natural, since she’s with her all day. But this has helped me realise that love alone doesn’t mean it’s the right fit, and that I need to prioritise what’s best for my baby’s development and wellbeing.
Thank you again — it’s honestly been so reassuring to hear your thoughts.

Zero child care qualification & zero experience should be your bigger concern

She isn’t a nanny let alone a mummy…

This sounds like the plot to a channel 5 afternoon film.

It’s always worth remembering that 49% of the population are below average intelligence… do not employ unqualified and inexperienced people…

If she doesn't understand developmental milestones that's a reason to not keep her.

But if she had children and got in the habit of "come to mummy, give that to mummy" etc. it can be really hard to shut off when talking to babies.🫣 I do it sometimes with other people's babies, and I'm mortified by it. It's almost like I think it's my name when talking to any child under two.

My youngest is 11, but I had 3 under 3 and the baby years were long and I still slip into it with them sometimes.

Slightly concerning that you’re still feeling guilty about it all. Ridiculous! Get her gone asap….she’ll be looking for the title of “wife” next as well as mummy.
seriously - she needs to be fired and you need to find a professional agency to help with your childcare requirements.

You are being unreasonable to pay this person to take of your baby

How did you end up with her as your nanny, op?

It's all a bit The Hand that Rocks the Cradle op... sack her

I've had nannies for years and it's really not worth it to have someone you are second guessing a lot of the time, and are sitting around worrying about. You really need someone you can just completely forget about (bar any very minor issues) because you have complete confidence in them.

Calling herself 'mummy' is so strange and inappropriate.

I have opted for a younger, more inexperienced many currently for my two 7yr olds. She doesn't get everything right, But the kids are 7 and it's a different ball game. And under 1yr old? No.

Your child is far too precious to leave with someone who doesn't have the first idea about basics.

Not true.

This is dangerous , an accident waiting to happen, tell her theres a problem with finances and get rid asap x

Why did you think this woman was suitable in the first place?
