Sounds like you are already sharing and generous with your child’s birth mother. Mother’s Day IMO is your families day. Your child has a birth mother who has present and available and that is a wonderful gift. But Mother’s Day is your wife’s day to celebrate her love and joy with a child she never dreamed she would have. Others may disagree - but I’m adopted - im 47 - every Mother’s Day for me was with the women who I ran too when I was as hurt or sick or sad - my birth mum is a great woman- but my mum is my rock. Kindly make it known on mother’s days you are doing your own thing - and if needs be the next weekend do something together. You have both braved societies norms and deserve to celebrate yourselves as mother’s and fathers on the days that everyone celebrates. I wish your family so much love and luck. Hxxx
