I got half way through reading your posts and had to reply.
Her mother is dead.
A drink at the pub is not plenty.
He has funds, a shared interest and a plan to do this for her for a special birthday.
No matter what you do if that goes it can’t be brought back.
It’s madness to cancel at this point. If you have pregnancy complications or some other valid reason then fair enough - and your insurance will cover the cancellation because it would be perfectly reasonable for him to need to be with you.
Paternity leave is two weeks. Beyond that you have maternity and he is at work unless you split the maternity between you.
There are going to be a pile of times you will have to muscle up and get on with being a mother (likewise for him if you are away for some reason). The newborn stage they sleep 16hrs a day, if you’re breast feeding that can be tiring but if not it is an absolute piece of cake.
When we had our first, beyond the 2wk paternity my DH was at work on 12hr shifts, 9am-9pm… at night he was sod all use because I was feeding. He did batch cook for me but that can all be done in advance by your DH.
He has the money for US open tickets and an extravagant trip.
Would he have the money to cover a doula or someone to help you if you are really feeling that marooned?!
I think that’s why everyone is getting short with you, you really do have to get on with it. To ruin this experience for two other family members… it’s being a bit of a primadonna and catastrophizing what having a newborn is like.
If there is nothing wrong with either you or the baby, what is the problem? If you aren’t confident in your ability to cope then hire a doula or somebody to come in and help (you will probably want a cleaner anyway now at least with the added workload).
To be honest OP it reads like you are already sidelining your stepdaughter and wanting your offspring to take centre stage.
You should have not tried to get pregnant until you knew this trip was clear. I know it’s slightly OT but either get married or have an equivalent legal document drawn up to protect you and the baby. If you split you are screwed financially and he has sod all rights or obligation.
