I’m wondering what people’s opinions are on a statement I read the other day?

The paragraph was basically telling people that it is hard to be in a stepfamily, there are past relationships and baggage to consider and stepfamilies are far more complex than biological ones. Which is all true and realistic and the sort of thing people definately need to realise and bear in mind.

But, the first sentence of the paragraph went like this:

“Don’t expect your stepfamily to work like a biological family for the reason that the stepfamily is a family built on loss.”

So what are people’s thoughts/reactions/opinions on that statement?
