I think all women should be encouraged to have their last name as a child’s middle name. If the parents have different last names and you travel with the children on your own, it helps to have your name as a middle name. Otherwise in some countries they will ask for proof you’re the mother, eg birth certificate, and that you have permission from the father to travel with the children. Surprisingly the country where I learnt this was England! Names are important legally, so don’t edit yourself out!
