“My husband wants me to stop breastfeeding my son. We have
daughters together, but he makes fun of my son when he cries for me
and says things like ‘he’s such a girl.’ My husband also thinks I
should stop breastfeeding because he says it’s stopping me from
losing weight. He isn’t open to the idea of talking to a
professional about this. Has anyone got any advice on dealing with
an unsupportive husband?”

Amidst other replies this mother got on the forum, eg. "Divorce
him!", she also received the following reply from a professional
psychoanalyst.
“1. Your third child is a boy and him as a father possibly has
had fantasies surrounding the relationship he would have with his
son. It appears (most likely because your son is still very young)
that you are living out your husbands fantasises, but he is not.
This could make him somewhat jealous and insecure.
2.This is further emphasised through his remarks of saying your
son is being like a girl when he cries for you. Your husband may be
saying this for two reasons – One being again he is not the first
point of protection or comfort and two, he would feel somewhat left
out of your special relationship.
3.With respect to your weight I’m not sure of the background to
the comment, but if you yourself have mentioned weight loss in the
past, then this might be a way of him trying to persuade you in a
positive supportive light (although it might not come across that
way).”
Psychoanalytic smackdown! Touche.
