Play-date issue!

[Parentslife]

So my 8 year old son has just moved schools because we wanted him to have more friends.
He was in a tiny, rural school of 28 kids so outgrew it. For context, he’s already socially well adjusted from extracurricular activities and the move has been successful. He’s made friends quickly but especially with one boy, who appears to be a really nice kid.

They hit it off and after 6 weeks, now refer to each other as best friends.
Then I met the Mum at a school event and there’s no easy way to say it, but although very nice, she’s extremely over the top and intense, aka crazy.

My son came home today and excitedly told me that the boy had invited him over tomorrow.
The Mum messaged me and told me she’d pick both of them straight up from school and I could collect him a few hours later.

Now I don’t even have her address or know her at all, so explained I’d be more than happy to drop him off after school and pick him up later.
I asked for the address and she’s ghosted the message!

Am I being unreasonable to not let another Mum pick my son up and take him to a home I’ve never been to?
Is this weird or would you be OK with it?

Thanks!

YANBU, OP. You need to know who will be around your son at that age, if you're not going to be there. Or you need to trust the other mum's judgement, which it doesn't sound like you do.

Most people are very nice and I would trust them to look after my DC no bother but it does no harm to be sure. There is a mother we know from outside school who is absolutely lovely and I trust her 100% but the dad (from whom she is separated) is a complete nightmare, there is a history of DV and he turns up periodically and kicks off at her and the children. So although we often do playdates, there is no way my child is going to their house unaccompanied - it's too great a risk imo. Another thing I have learnt is that dog owners can be deluded about how safe their dogs are around strange children, so I would never let my child go to a house with a dog unless I had visited first and trusted the parents to supervise closely or keep the dog away from my child.
