Sexing help

[Twilight]

Today I tried to sex Lilac’s babies. They’re 16 days old, and this is my first time sexing babies- and although I have read a bunch of stuff about sexing, I’m still unsure of whether I’ve sexed them correctly.

Does anyone know if these are correct? (Sorry, the photos are blurry- the babies are really squirmy!)

Females have half the distance between their urethra and their anus then males, as this is where the testicles develop. It often looks a bit puffy too.
These are 5 week babies but i put diagrams on them
