My fiance had to put the eyes in for me the first time when I just wanted to see what they looked like. When he finally got them in I was like OK, now I’m taking them out to finished painting and rooting her and he said " WHAT!? I thought they were in for good!!" LoL
His hands are big and mine are little so both of us working together got them in fine. Maybe you could find someone with small hands to help.
Also, if anyone ever has trouble with the sockets wanting to “not move out of the way” I take a small paintbrush handle and push it through to make it go behind the eye and that works for me.
