To get annoyed at my SIL

[Charmander123]

My SIL is a teenager (15) and I have a baby. Everytime she sees me she's very good and considerate with the baby. She's stayed at ours this week whilst her parents are at a wedding. She's sleep upstairs so doesn't wake up to he baby crying.
We love close so her friends can visit for a shirt time. She makes SO much noise/screams. And it's worse when they are around. I started asking very politly to be quiet as the baby was asleep/had a bad night. Which the quiet lasts 10 minutes :-(
It's really bad even just with us where I constantly have to remind her to be a lite quieter. (By day 2 she had woken the baby every nap ) it'd day 4 now and she's gotten no better. I'm usually very patient with her and we get along really well but eventually I snapped and told her to shut up otherwise she'll be the one dealing with the baby crying if she wakes her up. To which she now is calling me a bully. My DH agrees with me but she's very stubborn.

So was IBU or is she being a dramatic teen? X

Yabu, a group of teens is naturally loud. If you don't want baby disturbed during the day tell her to go to theirs.

It's not just with them (thry aren't even round that long) it's just all the time with her. X

Send her home.

She's 15. She can be alone for a few days.

It's your house so your rules but tbh, you are being a bit pfb.... the baby needs to learn to sleep through noise

Is there anywhere she can go while the baby naps? I would let her know when the baby is sleeping and tell her to be quiet or she has to go out during the next nap (daytime / safety permitting of course). It won’t work if you’re in the middle of nowhere.

But no, you’re not a bully or BU.

PFB, I was the same with dd when she was a baby, I now look back and cringe at myself.

Firstly I'd stop her friends coming round. Secondly I'd phone her parents and ask them to have a word as she won't be welcome to stay in future if she can't be quiet.

Noise from other kids is normal for babies. Ds was a noisy 8 year old when dd was born.

Your house your rules, I would have sent her home on day 2. Definitely would not allow her to have friends over if she can't respect the house rules.

You lasted 4 days before telling her to shut up. More patience than me.
Why is she screaming anyway?
No friends round and I agree with others, at 15 she can be at home alone for a while and be more bloody considerate.

When you’re asked to have her again say sorry but no. Teenagers aren’t all noisy and thoughtless but this one certainly is.

There’s a difference between a baby getting used to sleeping with a noisy young sibling around and baby who usually has undisturbed sleep being woken up by a 15 year old who is old enough to know better!

Yeah my baby sleeps through hoovering and lots but a sudden shout from her and a scream at her laughing at something g on her phone /being on the phone etc. Wakes/scares the baby

So, when she is on her own, she screams ?

Why ?
I can understand going off in peals of laughter or whatever when her friends are with her, but when she's just hanging about on her own ?

I can understand the baby needs to sleep through noise, I hoover and be noisy when mine sleeps! But to be that loud their waking them up every nap then that's not on !

If your in someone's else's home, you respect their rules !
