I agree that online (at least for me) is not the same. But would it not be preferable to have someone, even if it is not the same, than have to go through all the emotions and fear on your own?

If you do good work together (though the focus might shift with what is going on) and you feel his support, I'd say: something is better than nothing.

And yes, he might need to get creative and adapt re toys and art. Ask him. See what you both can come up with so you can still work together.
