Reverse Conlanging

As regular readers will be aware, I like Doctor Who and conlanging.
Unfortunately, these don't intersect much, as the TARDIS has telepathic circuits that can translate any language. However, here's an exception

Venusian lullaby

The Curse of Peladon was written in the days when, if you wanted an alien language, you made up some gibberish and hoped for the best. However, this is coherent enough to make some sense of it. Using the Doctor's translation Close your eyes my darling, well three of them at least! I've worked out the following so far

klid

child

kloklid

diminutive, used to express affection

klida

1st person posessed form, used to express kinship

kloklida

My dear child

pɹaθ

eye

paɹθa

paucal, used for more than two, but not necessarily a complete set, for which the plural would be used

men

you

mennin

your

klatʃ

close (hortative)

One thing that might be harder to explain though, is why it's sung to a slowed-down version of God Rest Ye Merry, Gentlemen.
