DD putting herself at risk, its giving me sleepless nights

Blow Harry Potter World. Your DD should be putting her pregnancy first and not undertaking such a journey on her own at 37 weeks pregnant. I think she’s being very irresponsible but come the time I doubt she’ll have the energy or enthusiasm for such a journey.

Although I think it's an odd thing to want to do, too.

Generally, mine used to tell me what they'd done after the event. It saved me from a lot of angst although I was horrified when I heard about some of the escapades afterwards.
😲

You describe her as a health care professional so presumably she knows whether this trip is risky or not. I would share your concern but keep it to myself as daughters can be very resistant to maternal advice!

I agree with what GrannySomerset says

We never stop worrying, do we.

My DD has just had a baby at 38 weeks. By 37 weeks she could hardly put one foot in front of the other, let alone walk around HPW. And the journey??
I hope your SiL can talk to her.

I agree it seems like a curious decision even with a straight forward pregnancy. I would definitely not have wanted to treck 200 miles on public transport to spend the day walking around a theme park. Is she likely to enjoy it? Has she thought it through?

The thought of her being attacked however would not occur to me.

If this were my daughter I’d never even have considered that she’d be a target for an assault or attack, so I can understand why your DD thinks you’re over-reacting if you’re giving that as your main cause for concern.

But I would be very worried about her taking on this expedition so late in a high risk pregnancy. As others have said though, best bite your lip now and just hope that she might think twice about it herself as she gets closer to the date. You’ve told her how concerned you are and you can’t do any more.

Can understand you worrying about the pregnancy but being attacked or assaulted is quite a way beyond imagination
I certainly wouldn’t have been wanting to do that journey at 37 weeks as I was so tired and lifeless at the end of pregnancies but she’s a fully fledged adult and nothing you can do or say just like nothing I could do when my youngest told me she was bungee jumping over lake Victoria
I think she’s a bit daft to go at such a late stage of a difficult pregnancy as that could prove a bad move but it’s really between her and her husband ….what does he say?
Please don’t be in a stew until the end of April it’s a long time and going to spoil your life
We really shouldn’t know everything our grown up children’s are doing with their lives a pity she told you about the trip

As an adult it's her choice she may feel less like doing the journey as it gets nearer to her due date. I personally would not chance it but not because of any fear of attack she is in central London and as you say she is well educated so will have worked out which tube ect she needs in advance. London is not a dangerous city.

She's not thinking straight, but you'd best be quiet having already given your opinion. Our daughters would go to spite us if we kept on.

I think the risk of attack is slight, but the journey is likely to be difficult for her, and she’ll arrive at HPW exhausted. All the same, as an adult it is up to her, and if you keep on at her she is likely to get annoyed (or my daughter would, anyway).

I don’t think she’s vulnerable to attack, but I do think she has chosen a tricky time to be going on a day trip.

I’m sure she will be being monitored quite closely. Maybe she can run her idea by the midwife/ doctor?

I feel for you. It’s so hard for us to bite our tongue when our AC is taking a risk, but we probably wouldn’t have wanted advice in our day either.

I don’t think you are overreacting, but it’s her decision. Hopefully all will go well, but if things go wrong, anything you might have said will be cited as a cause. If you had said nothing, you would have been at fault for not warning her.
I wouldn’t have gone at 37 weeks, simply because of how tired and uncomfortable I felt. Your daughter may well change her mind, but you’ll have to leave it up to her. Sorry you’re losing sleep.

While the thought of attack wouldn't even occur to me, the risk of a long journey at 37 weeks in a high risk pregnancy is really silly.

It sounds like you have voiced your opinion already, I would leave it at that. I'm sure her husband would have his own thoughts as well, and may try to discourage her.

She’s risking the life of her baby. Highly irresponsible in my opinion. Can her husband/partner not get her to see that the safety of the baby is somewhat more important than visiting HPW?

Its Harry Potter world not the moon. I have done the journey and it's very straightforward.

It’s her business in truth

Is 37 or 38 weeks considered early?
I do think you're catastrophising a bit.

Tricky one. I think she is making a poor choice. Could you back off a bit and see how that goes?
