Would you be ok with Dh taking dc on a flight for the first time

Of course! I’d enjoy the time to myself.

I am amazed you’ve never had a night away from her in 5 years!

I think there were men that took their children on the Titanic alone , that didn't end well .But they can manage . Women are not mythical creatures . I wish they were but they're not. Alas they're not or the ship wouldn't be such a disaster .

Yes but I wouldn’t be worried my dh couldn’t cope. I would just miss them.
if she’s going to family there are people who will love and help look after her. She’ll love the attention.

FaceTime and call x

Enjoy this time in your early pregnancy. Rest, relax and eat well.
I hope all goes well xxx

As others have said, miss yes, worry no.
I had to go back to work in a job that requires travel when my boys were both babies. I was the other side of the Atlantic by the time the first was 6 months old, and snowed into a European country when the second was 7 months old. I missed them both horribly, but had every confidence that they would be fine with their father. So for me, it is unusual that by age 5 you have never had a night away from her. Not wrong, but unusual.

As you are pregnant now, you may need to start 'separating' yourself a bit, for the longer term good of your family. To fully trust your H that he will look after her, and know how to calm her if she is upset for any reason.

She'll be with her dad. Why wouldn't she be O.K.?

In your shoes, of course I'd miss her. But that isn't a reason for her not to go.

Flight - not a first I’d care about, in fact as small children are hard work on flights a bonus to miss that
First time apart for 3 days - can see you might be worried. I have 2 DC who would have been fine with this and one who struggled to be away from me. In fact she’s 22 now and still likes a high level of contact! You could do a trial run of shorter time/same country to acclimatise
Meeting husband’s family - I’d be a bit sad to miss out as it’s a big milestone but not worried unless I knew something averse about the family

Miss yes. But by this time I would have always been away on work for up to 2-3 nights and DH for longer. Has your DH been away from home? Presumably your DC has also been in school so isn't around you 24/7. As long as DH is competent I wouldn't worry at all. I might miss them, and the whole adventure but I wouldn't be worried. For the record DH first took DC1 on a flight without me at about 2 to see the parents (I was at a conference), and since then has taken one or both away without me.

Also 3 nights is not long- it's an extended weekend yes? For a little baby with no sense of time that might be long but not for a five year old.

I don't understand the question. Why wouldn't you (I assume he is their dad)? What an odd question.

She’ll have a lovely time. She’ll be fine. Congratulations on your pregnancy.

Why not, she is with her Dad? I am separated from my exH and he has been having our DD on his own in his new house since she was 7. I also used to travel for work from when DD was 2 and she stayed home with her Dad 2, 3 or even 5 nights. It was tough (single parenting is) but they survived and whilst pleased to see me back, my DD was never upset that I'd gone.

Edited to add that of course I miss her. I miss her now she is 13 as much, or maybe more, than I did when she was 3. I chat to her on the phone and hug her a lot when she gets back.

Miss my child yes. Worried that are with a competent parent who is more than capable. No

I wouldn't worry about the DC for a second if they were away with DH, he's their parent, same as me. Is your partner not very involved in the day to day parenting?

I took DD away by myself at 4 to visit family, her first flight. DH was slightly envious he was missing the excitement, but no other issues.

Miss DC, of course. But I’d see this as the start of her being a little less dependent on you. Otherwise you’ll be the one whose DC can’t cope with a one night school residential in Y4 and she’ll miss out on so many things.

I'd relish the break! Dh took ds to Oz when he was 8. They had a blast

Would no one else be worried and miss their child 🙈maybe I have issues, I still see 5 as young to be away from me for that long in another country. If something happened I couldn’t be there
Worrying and missing are totally different things. I'd miss her, I wouldn't be worried. Nor would I send her away to another country with another family member but with her own dad of course it's fine

I would miss my child, sure, and tbh I'd probably also feel sad that I didn't get to be on their first flight with them - just to see their excitement etc! Not that I'd tell them that and spoil it for them. But worry, not really, DH is also his parent and capable?

My DC went with GPs to Italy for a week when youngest was 4.

Yes I missed them.
No I didn't worry as completely trust my parents.

As she hasn't spent a night away from you in 5 years I'd take it as a great opportunity to change that.

You're projecting your upset on not seeing DC for a few days onto her.

She'll be fine. Totally.

Don't make her miss out because you'll miss her.

Of course parents (fathers as well as mothers) miss their dc when they're away from them. And as you will be away from your dd for the first time I understand you may feel anxious.
I have been a single parent to my dd since her birth and she was 5 when she first stayed away from me. I was anxious before hand because it was an entirely unknown experience but it went brilliantly.
Your dd will be with her other parent. A parent she has lived with all her life. She will be fine.

Miss yes, worry no it's not about me

I'd miss my child, but I'd also enjoy the break. I wouldn't be worried because there would be nothing to be worried about.

Think about your husband and daughter having a great time away. Stop making it about you.

I'd miss them of course, but I totally wouldn't stand in the way. It would be a me problem. I'd get over it.
