I would think a hot shower would be fine – it’s not prolonged.

I’ve heard of not having a hot spa/super hot bath before, so I guess in regards to showers, as long as it’s not TOO hot, you’ll be fine. I once tried to go in a spa and felt really ill when I heated up, so I believe your body will tell you if it’s too hot for you.

I’ve never heard of this. I don’t think it would be a problem. I was told that when you are breastfeeding, warm showers increase milk production.
