I had a successful assist feed today. I combined a lot of the useful info you peeps provided.
1. Firmly held the base of his skull at the neck
2. used a q-top "bar" to pry his mouth open
3. Lovely assistant placed the pinkie in his mouth towards the back of the throat
4. I removed the q-top "bar"
5. I pressed his head and tugged the pinkie to lock it in place
6. I straightened him out and slowly released him after he calmed down a bit
7. Success on the second try! First try he thrashed it out, but I didn't straighten him out.
I will see if there were any negative repercussions, but thanks to everyone that helped out with this. I feel like I helped this little dude out.
