Husband taking son abroad

[H930]

My husband has booked to take our four year old son to Belgium on the Eurostar as he’s fascinated by the whole idea of it. It’s just two days and one night. I’m staying home with our baby.

It’s just occurred to me whether he will have any problems taking our little boy abroad without me? As in, do I have to somehow explicitly give permission? A quick Google has only yielded results for separated parents. We’re married and both have PR, all have the same surname etc.

Any ideas from anyone who has done this? Will it just be straightforward or will my husband be questioned in some way?

It makes me so happy to think of them on their trip!

My dp and ds used to go on "boy's days out"- they had such fun. Sometimes they didn't tell me where they had been- it was a "boy's secret"
They went on one to The Gibson Garage a couple of weeks ago- DS is 23!

Meant to tag @H930 in my last post!

I have travelled multiple times alone with my kids when I had the same surname and then later when I had a different surname. Never any issues.
