I clicked through to the actual research, which is here (only the abstract, you need to pay for the full paper): www.sciencedirect.com/science/article/abs/pii/S0022347622010009
The reason I am posting this is because I believe the more informed we are, the more confident we can be in our choices as parents. I hope it helps someone.
