I'd like to know what words or phrases use when describing the following situation.
Consider a boy trying to build a sandcastle, for example. He in all probability can't make it at the first attempt, the building might be destroyed quickly. Now if his parents instead of guiding him and help him to learn by himself, make the sandcastle themselves. They did this just for sympathy that their child doesn't experience failure, but in fact, they degrade the child's self-confidence and ... .
I called the parents' action in such situations "destructive sympathy", the action is done for sympathy but in practice is destructive. Again, I'd like to know what words or phrases are used to describe the parents' action.
Thank you in advance!
