It depends on "toxic relationship" or not, plus prayer, meditation and inner instincts.
Right from the start, none of this is a forever thing. Even as a parent of grown children, some months without any contact, even through birthdays or holidays, is okay.
Now I buy gifts through instinct rather than obligations. There is no "you haven't even bought your own parents birthday gifts!" arguments as I haven't bought any birthday gifts for anyone (other than DS11) or even sent a text message on a birthday in quite some time. Freedom from traditions that weren't bringing us any closer.
I celebrate life each day, right where I am. I also buy inspired gifts when I come across them and bring or send them through instinct, too. No favoritism gets involved. No rhyme or reason, other than pure instinct.
