What Christmas song has the first line initials wcithltromlis?

Answer 1

I believe this song is What Child is This. However, the initials for the first line vary just a bit and are wcitwltromlis. (The bolded w is an h in the question and may be a type-o).

The first line of this song is "What child is this, who, laid to rest, on Mary's lap is sleeping?".
