Thanks! no hurry (if ever). Treebeard would likely agree with this course anyway

(...) I think Treebeard's statement might be both a repetition of a general saying at the time, and may also include grandchildren among 'children'. Because then, in addition to Celebrian, C & G have further 'offspring' of Elladan, Elrohir and Arwen.

I was wondering about that too: it may just be something Ents generally say to Elves. Too bad JRRT didn't explain this a bit more in Words, Phrases, and Passages.
