My husbands ex wife

My husband and his ex wife were married for about 5 years, within those 5 years they had 2 kids my step-daughter who’s 6 at the moment and a son they had that passed away at birth. I am currently pregnant and due end of may. She told my husband that she wants us to send her pictures when she’s born because she knows the baby is going to look exactly like her son that passed away and wants to see if it’s reincarnated son, then she added that all my husbands kids looked just like him. The way she said it felt really weird to me and my husband. I don’t know if it’s the fact that I’m hormonal or I’m overthinking it but I don’t want to see her now that I’m pregnant and feel strongly against letting her see my son until I feel comfortable. I just don’t know if her intentions are pure.

She’s the type to post about her life all over social media and I don’t want her posting my sons pictures out there until I feel comfortable.

Would you ladies send your husbands ex wife pictures of your new born?
