My baby won't go to sleep unless she can see me!!

[Megane1991]

Looking for any tips or advice!
My baby girl is one next week and I feel she is going through some separation anxiety!
When she was around 4 months she was sleeping brilliantly as she's got older she's started to regress sleep wise, but this last month has been the worst!
She didn't go in her own room until she was around 10 months due to her having to share with my 2 year old. Anyway we bit the bullet and put her in there, but she will not go to sleep unless she can see me. Even if I get her to sleep by rubbing her back she will wake up screaming after I've left the room and then as soon as I walk back in she will settle straight away. This happens right the way through the night and I am losing the will and exhausted especially now that I've gone back to work full time.
Against my instincts I tried controlled crying but this doesn't seem to be working and I'm worried that it's just causing her separation anxiety to be worse! It's also not fair on my son on a night to hear his sister crying.
Please help, any advice would be appreciated!

Can you move her back into your room for a while you must all be exhausted - I imagine she is disturbing the 2 year old as well.

My D’s was about 18 months due to various circumstances - he picked out Thomas’s the tank engine things and was quite excited although didn’t stop 3am wake ups into my bed - it was better

What would get you all the most sleep? Is it moving her back in? Then I’d do that.

Do whatever gets you the most sleep. There is no right and wrong way to get children sleeping. She won't be in your bed forever, just try again in a few months time.

It’s all very well saying move her back in but separation anxiety can take root and she may end up being like that until she is 2, 3 or even older unless it’s nipped in the bud quickly. Otherwise you may get a child who refuses to sleep alone. 2, 3 or even 4 year olds can be very difficult to get to sleep unless good habits are formed. Which may mean a few hellish nights. The one I feel most sorry for is the older toddler.

I have thought about moving her back in with us but as was mentioned I was scared that it would cause a bad habit and that she would never want to sleep alone. It's a really difficult one. In all fairness my son sleeps like his Dad and he sleeps through it, it's just when he's first going to sleep that it disturbs him so we've changed the routine slightly so that he's asleep by the time we take her up. Last night was slightly better with only 3 wake ups! And the last was at 5am so we just brought her in our bed then where she slept soundly next to me. Thanks everyone for your comments, I guess I'll see how she is for another week and then I may have to just move her back in with us. Doesn't help that she's getting a tooth at the moment and I think that's what's waking her up aswell and making her realise that I'm then not there.

She is clever and knows what she needs to feel secure. If possible cater to it by cosleeping / room sharing. If that means you'll all get some good night sleep. And try to transition. Her back once she is sleeping well and settled.

"Never want to sleep alone". She will 100% as she will want to share her room with sibling and be independent. It varies but some children from 2.5 will love fheir own room with their own special things. It won't be forever.
With DS1 we got him a specialist night light / lamp and bedding and rug of his choice. Made him excited about it and he loves his room. We haven't moved him yet as I just had a baby and don't want to make him feel like he has been booted out.
