Obstipation tends to make the elderly obstreperous.
Congratulations on your twins. As twin births are more complicated and hazardous than singletons, it is probably wise to seek a country with high level medical care.
I suggest you contact Trinidad and Tobago's NHS and find out from them if there are reciprocal arrangements with the UK NHS regarding coverage. Otherwise, it is likely to be expensive if you do not have other medical insurance.
I wish you the best with your new additions to the family.
