Can't handle partners daughter. Advice please?

[Jagerbombfobreakfast]

My partner has been staying for a log while. Last night was the third attempt at his daughter staying here overnight.
1st time went great. 2nd time she was testing the waters. I wouldn't say naughty but more sneaky and innapropriate.

She stayed last night and I just can't do it again. She stayed in with my 3yo as baby needs their own room. She is 5 and kept taking her knickers off. Whispering things to my son about our relationship as I walked past the room about us getting married etc which we have no plans to do. I asked her to get in her own bed and went back up to find him in her bed with her whispering things to him again.
I don't know if I'm being OTT but it's not her place to be putting those things in his head and I'm really not comfortable with her being there. We don't have the room for her to sleep anywhere else. What do I do?

I don't really understand the situation/problem, could you have another go at explaining?

People really should give thought before having additional children when relationships with young SC have not been nurtured and developed with the parent and new partner this seems to be a regular problem that additional children are quickly thrown into the mix before the child can get their head around new partners and step siblings.

The baby may not have been planned... It happens.

Hi op

Welcome to the step parenting board
I myself was roasted alive on a spit the first time I posted here !!!!

No we don't know the background
And the world is never black and white

So this is how you feel about your dps daughter right now ?? . You obviously DONT WANT to feel that way else you wouldn't be posting

So that's a good start right ? You can take it from there .

I am assuming you wanted a bit of advice ? Constructive responses ? Shared experiences ?
Perhaps not to be " told off "

I know it is difficult and stressful
And little girls who feel threatened by a new lady in daddy's life ( not to mention 2 other DC who get to live with him and she doesn't ) can appear to have a swivelling head ( expecting to be roasted alive again for saying that )

My DP has kids
My child has a step mum
It's all a work in progress at times I do know that .

Please please please try if you can to see things through her eyes . Not look at her behaviour but ask yourself Whats behind
She must feel terribly insecure in my view .. She's bound too .
5 is a very little girl still .

Could you try to love bomb her a little ? Get her involved with you helping with the baby ? help her to feel important .
Nice duvet covers / nightie etc she gets to choose ?
I am not saying you haven't done this .

I know you have your hands really full.
Gather up all your patience And give it time

...and Jäger has not revisited this page to answer any of the reasonable questions being posted, hmmmmm

It isn't usual for a child to wear knickers to bed. Why is this an issue for you? They are tiny children. If you aren't comfortable with her wearing a nightie without pants (why?) then get her some pyjamas.
She's a little girl who needs some reassurance about her relationship with her Dad now that you are all together. the rules at her house will be different to at yours and she's too little to grasp all the differences at first.

This is sad, you are sad..you need to walk away, you shouldn't be a sm
