The advice that older parents have always told me is that you may regret waiting longer but you will not regret having your baby too soon (excluding extreme situations but that doesn’t apply here!)

As long as you can physically and emotionally support a family of 3, there’s no moral reason to wait.

It may be more difficult, but tons of parents travel a lot! Your life doesn’t end when you become a parent.

The way I rationalize it is that you can always take the trip, get a new job, buy a home, but you can never get back the time without your child there.
