And today we conquered the collapsible tunnel! It took about two minutes of building him up--starting with it completely open and him running through to stretching it out and letting the cloth barely touch his back to finally having him run through the entire tunnel with the cloth draped completely over him.
He did get scared once and tried to go back the way he came, but by the second time, was racing through it like it was nothing at all.
I definitely think the progression from the non-collapsible tunnel to the collapsible tunnel was the trick. I couldn't be prouder of my little guy
