Corona they are not talking about a man using a feeding tube taped to his chest, they are talking about supporting a transwoman taking a cocktail of drugs to induce a synthetic "milk" supply to "feed" a baby, coupled with the other hormones that the transwoman may also be taking.
The main concerns are that a) there are no studies on the effects of long term and large dose exposure to these drugs for infants; b) a male body is unable to produce this "milk" in sufficient quantities to actually nourish and support the child's growth; c) the disruption to the actual mother/baby breastfeeding bond.
I totally sympathise with your personal journey, I struggled massively with breastfeeding both my children: my first child I lasted 8 weeks, through multiple bouts of mastitis and a breast abscess that ruptured spectacularly in the shower one morning requiring multiple hospital trips to have the abscess drained and now, over 6 years later, my breast is still noticeably (to me) misshapen where the abscess had formed. My second child I lasted 5 weeks when the mastitis started again and I decided to stop through fear of the same thing happening again and putting myself through further pain, both mental and physical. I still feel guilty about it to this day and if you try to talk to me about it I will inevitably break down in tears - I'm tearing up thinking about it all as I type this now.
I believe I had undiagnosed PND as a result of all of this, something that still causes me issues to this day. In fact I have only just this week had an assessment with a therapist who has diagnosed me with "high levels" of anxiety and referred me for CBT as he says my symptoms are indicative of my brain struggling to process something, and I truly think my breastfeeding issues are a part of this anxiety.
