If adults are exposed to 0g for months they suffer a number of problems,
including bone loss, deconditioning, etc. Most of these aren't a
problem unless you return to Earth.

However, there are 0 data on the effects of 0g on children. They would
certainly grow up too weak to visit Earth without a wheelchair or worse.
If you did that to your kids on Earth, child protective services would
take your children away from you, and for good reason. It's child abuse.

First time I've heard of this. There have been some plants that have
gone full cycle in 0g, but some work, some don't. Handling a chicken in
current space stations would be quite a trick. Do you have references?

Maybe some day.

To raise healthy children.
