If the water is to hot it can overheat the baby if its directly on the stomache, think of it as cooking him/her, that's why people don't get in hot tubs when they are pregnant.
Is there something wrong with taken a hot shower to the bely??
Showering in hot water is fine, as long as its not directly on your belly. I do it every night. And it is so relaxing and helps me go sleep better afterwards.
I do it every night. I just stand so the water hits my back and not my belly. And I take anywhere from 10-20 minute showers
