In the assumption they’re fleeing to a country with reasonable human rights.

And leave a small child behind in a war zone?

Obviously with the expectation that their family can then safely come to the UK once their asylum claim has been approved, as was the case until now

I wouldn’t leave my child behind. I would try to get the child to safety. That is my point of view so don’t judge me just as I respect your different point of view.

They are trying to get their child to safety via a previously approved and safe route. That's literally what they're doing. This new rule stops them from doing that

As opposed to risking their child's during passage in an overcrowded dinghy?

It’s a horrible choice I agree - leave behind a child in a war zone, claim asylum in a safe county or try to cross the channel. It’s a choice I’m glad I don’t have to make.

During the revolution my family escaped, it was common. Parents were aware that their own escape was fraught with potential dangers & chose to leave children with trusted relatives until they could be safely transported for the protection of all. Don't judge without walking in those shoes.
