My step-sister had a baby 7 months ago. My step-mum and my bio dad live close to her and as such spend a lot of time with one another.
FaceTime with my dad today, and he's at her house holding my baby step-niece. I find this really painful, whilst knowing it's quite an irrational way to feel. It seems to bring back old feelings of being replaced, and I worry he'll have a lesser relationship with my children. (He absolutely loves my children but it does still sting).
Also, I'm a bit jealous that she has loads of help on hand whereas I've had none. My fault and choice one could argue, I moved counties (however my dad did move towns when he and my mother divorced so there's always been physical distance between us).
Not sure why I'm posting this. Maybe some other step-daughter mums feel the same?
