Who is the forgetful Mrs. Docherty in Magic Nanny 2?

It was in the last scene of the first movie that the bell fell into the hands of a baby named Aji. Later, she said thank you, Aji, for letting me stay with you! So this is a baby for sure! The "rules" that the baby knows are all told by the family! Sigh that Mike doesn't live long and exists like a god! ! I love this movie! Brother-in-law is Harry 4 as Voldemort, the protagonist is Sybil, a divination professor, and Professor McGonagall, but he is a little old!
