Here's a suggestion you would only find on Apug. It may work pretty well with this negative, so if you are up for a bit of an adventure, read on.
Print a full sheet striped by 1/2 stop increment test exposure using your Grade 5 filter, and a piece of opaque mat board. Never mind the lack of highlights, just find the exposure that puts your blackest blacks where you want them..
Expose a full sheet at that exposure. Then without moving the paper make another striped test print using your 00. Somewhere in this print the baby will be perfect.
Make a print, exposing the paper with the exposures you have determined using both filter grades.
(you will be exposing the paper twice, once with the 5 and once with the 00). Burn in the corner when you print the soft exposure. Dry it down, check it out, and alter future exposures to taste.
