DP sleeping over

[Rainydayss]

Any anyone had experience or know how to deal with DP sleeping over when DC aren't used to it?
To put into context, I've been divorced 2 years, one DS who has the habit of getting into my bed during the night.
I'd like for my DP to start to stay over, maybe once a week. My DS is only used to me being at home,even when I was married my ex worked away a lot. DS has met DP a few times but I'm scared of taking the next step.

When I did it with my DC we went away first and I set up some dolls and asked them where they thought everyone should sleep.
They put DP in my bed straight away and didn't bat an eyelid.
They rarely come into my room (too busy trying to get downstairs to watch telly).
They had got to know him first and feel very comfortable around him. They were 5 & 7 when they met.
Kids just think of it as a fun sleepover really, just like they have sleepovers.

He doesn't need "weaning off" sleeping in her bed, he'd stop by himself as he gets older. He's not going to end up 45 and still getting in there .

They don't stay little long, and he'd probably stop naturally when he starts secondary. I think sometimes we rush on to the next thing and don't appreciate the time and good things we have. They grow up so fast.

Since op's only just started the introduction process, I would just take it slowly and gradually spend more time together.
