This isn't and shouldn't be about it being an option for trans women though, but about what is best for a family and especially the baby. As I said, it's very rare that the best issues won't be formula
A male (ie trans woman) trying to breastfeed because it's the 'womanly thing' to do isn't for the benefit of the baby and shouldn't happen. Theres also a lot of risk of it being for sexual kicks. If you thought i was a fan of trans women lactating, I'm not. I just want a scientific approach taken in the first instance.
In the same way, a grandmother relactating too help out her daughter = fine. Doing it to drive a wedge, or to engage in fantasizes about it being her child = nope.
Maybe the answer if it is safe, is the only men that are allowed to lactate are those that don't want to but do so with actual reluctance. It's too hard to police.
Theres also a huge difference between (1) a woman relactating after a long time, (2) inducing lactation for the first time in a woman (3) trying to get a bloke to lactate. Number 1 is like restarting an engine (I haven't breastfed in 2 years but I can still lactate a little, and could easily up this). Number two is like starting an engine. Number three is like bringing a horse along and pretending its an engine 😂
So whilst I don't personally have the ick issue for a dad breastfeeding, I don't think it's likely it's going to work for a safely or very well. If it is safe, then in rate octaves I don't have an issue with it.
Ps: obviously males lactating is great for the dairy industry. Maybe we can get those boy babies to grow into lactating bulls. Actually, maybe we should test how safe and popular "bull juice" (🤢) is with the general population before we give tiny babies the human equivalent.
Who is up for a flat white with extra bull juice? Strawberry bull-juice shake?
