Is this an inappropriate book for a 4yo?

[GreenCereal]

My mum has sent this for DS’s 4th birthday. It says on the front cover it is a road safety story, and is called the Rascally Hedgehog - a young hedgehog called Timmy keeps crossing the road to meet up with friends at nighttime. I’ve attached the last two pages where DH and I thought wtf?

I called mum to ask if she’d actually read it, and she said she thought it was a good book and I could just change the ending if I didn’t like it. Nevermind that DD7 usually reads to DS and I probably wouldn’t show it to her either?

AIBU or am I being too precious?

I'd save it until he's 8, when he'll find it hilarious.

The thing is, it's incredibly safe and easy to navigate in many Asian cities (Tokyo, Seoul, Singapore, etc) compared to British cities like London. Children can roam freely and commute at a young age with an incredibly tiny chance of anything bad ever happening to them. There is also a communal culture of adults helping unaccompanied children.

The children still have to be taught to recognise actual danger though, but given how peaceful and safe everything usually is, the scare tactics and literal examples (e.g. of what a paedo might want) are to make them take it seriously. No comment on whether that's actually traumatising for them though – I don't think so at all, but of course it's hard to say.

She meant well but......
