So I took my partners car this morning and there was a booster seat in the back of his car.. and his kids are older.. teenager and other one in their 20s. My daughter has been in his car but I don’t ever remember her bein in a booster seat is this dodgy lookin??

Ok sorry Idk if that's an age for a booster or not. I don't drive. But if so that could be the reason. Just ask him! Not in an accusatory way.

Op why are you with him you do nothing but worry and question everything

Maybe he bought it for your daughter then. If you can't ask him about it that's most odd.

Ask him we cannot really say. It could be for a niece or nephew. It could be he has a younger child or it could be that he lends his car to someone.

He doesn’t have any nieces or nephews this why I’m confused

Is your daughter of an age where she might need a booster seat? He could have one left over from his kids and thought you'd find it handy?

Or the other option, is you suspect he might have another secret younger child?

Why would he lie about that? I mean you should just ask him about it. But if you don't trust his answer then the relationship is going nowhere.

That bizarre that you start a thread, but haven't just asked him.
Why is that?

Well he obviously drives with a child in the car regularly.
