I don't know the song, but after hearing it I'm inclined to agree with Caoimhín and WFM.

These are just my thoughts ...

Iarla said too that it is a suantraí, so it is probably a song for a child about a child.

I think "súp" is "soup". That corresponds with Pádraigín's "sú", as that is the word used for soup in the North of Ireland.

Bog braon - is warm the milk. This is likely to be an older child, a toddler, not a nursing infant.
I don't know if the word at the end is "blais" but if it is it fits well with warming the milk and tasting it first to see if it's too hot before giving to the child.

It was common in the past for people to go barefoot, especially children. And feet would have to be washed every night.
There was a special saying/warning before throwing the dirty water out the door in case somebody was outside.

Bog braon, bog braon, bog braon don seanduine,
bog braon, is blais féin, is é a thabhairt don seanduine.

Curfá:
Cuir a chodladh, cuir a chodladh, cuir a chodladh an seanduine,
cuir a chodladh, is nigh a chosa, is bog braon don seanduine.

Ubh circe, ubh circe, ubh circe don seanduine,
ubh circe, is blúirín ime, is é a thabhairt don seanduine.

Curfá

Feoil úr, feoil úr, feoil úr don seanduine,
feoil úr, is braon súip, is é a thabhairt don seanduine.

Curfá

Bog braon, bog braon, bog braon don seanduine,
bog braon, is blais féin, is é a thabhairt don seanduine.

(Sin a bhfuil)

Warm a drop, warm a drop, warm a drop for the old man,
Warm a drop, taste it yourself, and give it to the old man.

Chorus:
Put to sleep, put to sleep, put to sleep the old man,
Put to sleep, and wash his feet, and warm a drop for the old man.

A hen's egg, a hen's egg, hen's egg for the old man,
A hen's egg, and a little dab of butter, and give it to the old man.

Chorus

Fresh meat, fresh meat, fresh meat for the old man,
Fresh meat, and a drop of soup, and give it to the old man.

Chorus

Warm a drop, warm a drop, warm a drop for the old man,
Warm a drop, taste it yourself, and give it to the old man.

Arán úr, arán úr, arán úr don tseanduine,
arán úr is braon sú is é a thabhairt don tseanduine.

Fresh bread, fresh bread, fresh bread for the old man,
Fresh bread, and a drop of soup, and give it to the old man.

Hadn't thought of the older child being given cow's milk, but in any case Pádraigín Ní Uallacháin's translation should still say "warm a drop" rather than "a warm drop".

Yeah, a big clue that the song is not about a small infant, is the fact that he is given warm milk, a hen's egg with butter, soup and fresh meat before being put to bed.

Yes, well, I wasn't the one who mentioned a "bald baby" in the first place. (Neither did Pádraigín Ní Uallacháin in her liner notes as far as I can see.)

uh-oh, it looks like Caoimhín has got some explaining to do

And there is also an alternative or extra verse in some versions:
