The Three Day Nanny

No-nonsense nanny Kathryn Mewes returns to help more desperate families as they face toddlers that would challenge even this modern-day Mary Poppins

No-nonsense nanny Kathryn Mewes returns for a third series to help more desperate families as they face toddlers that would challenge even this modern-day Mary Poppins.

First up are Luton-based Livia and Paul, who are battling with their two-year-old son Sebastian. He rules the roost at home, making sure he gets his own way with some spectacular tantrums.

He will bite, kick, run off and, if all else fails, hit his own head on whatever hard surface is in range.

After spending many years trying to start a family, the couple just want to love and treasure their little miracle.

Kathryn needs to introduce some discipline, but Sebastian proves to be one tough toddler to tame.
