I dont see nothing wrong with it. It’s a day celebrating mothers and as the mother of my child, why would I not want to celebrate her by giving her either a gift or a card.
From my prospective, regardless if we are no longer together or not, as the mother of my child she will always be honored and hold a special place in my heart… and if the person im with cant see the reason in that then she have a serious problem.
What some women cant understand is that in order to fully embrace the child, you must to a certain extent also embrace the mother of the child as well. You dont have to be BFF, but you can never be truly close to the child if you dont really acknowledge the childs mother.
