Een Engelse variant

Two friends are chatting:
John: How old are your children now?
Eric: None of your business
John: Oh come on, it’s for the Friday Puzzle.
Eric: Oh ok. Well, there are 3 of them, and if you multiply their ages together you get the number 36.
John: Can you give me more information?
Eric: OK, the sum of their ages is exactly the number of biscuits we just consumed.
John: That’s still not enough.
Eric: OK, my oldest child likes to watch the ‘Bets you always win’ videos on YouTube.
John: OK, now I have worked it out.
How old were each of Eric’s children?
