Question

I have toxic in laws. All of a sudden, they are being nice towards me.... turns out they are wanting alone time with my 18 month old. Due to all the inappropriate behaviour, I’ve never felt comfortable leaving her with them and they’ve only seen her 4 times this year - they don’t have a bond. She’s just too young to be left with them, especially with things being so rocky. 
I am trying to word a polite NO to them, but struggling a bit. I’ve written the below so far, help me please make it sound a bit more sensitive.... but I also dont want to write any false promises in for the future - things have been really rocky with them. Obviously, if they actually start behaving normally, things will change. We’ve never confronted them over anything (dh choice), we’ve just avoided seeing them.
“Thank you, that’s a sweet gesture. Unfortunately we just don’t feel comfortable with that at this time, but I’d just like to say thank you for offering”.

Answer

It sounds way too "business" and lengthy to me. If it's a text, I'd say something closer to this... 
"oh, you're so sweet to offer, but I'm not comfortable leaving her alone yet."

Answer

“Thank you that’s a sweet gesture. Unfortunately we don’t feel comfortable with that at this time. Perhaps we can all find something to do to spend time together so you’re still able to spend quality time together” ( ?)

Answer

I’d say something along the lines of:
Thank you very much for the offer. Unfortunately, we just aren’t comfortable leaving her overnight without us yet. If you’re still wanting to spend time with her we can definitely arrange a time for all of us to get together. 
You can omit “overnight” in the second sentence if you think that they’re going to then reply and ask to have her over without you during the day and you’re not comfortable with that either.

Answer

I would of said it actually the way you did! Sounds perfect

Answer

I think that’s nicer than I’d think to be. If my husband refused to address the issue with them, I’d refuse to answer their texts when it was something like this. Him not being mature enough to handle a boundaries conversation  is putting you in an awkward situation to have to be the bad guy.

Answer

You should add something about being you not feeling ready to let her be without you just yet? So it doesn’t feel like you just don’t want THEM to be alone with her. I feel rude all the time and don’t want to hurt anyone’s feelings haha. I’m sure the way you said it is good too.

Answer

I'd say thank you and offer that they spend more time with her in your presence before having alone time with her.
