Parents know all too well that a child's likes and dislikes are hard to predict and what delights one child is likely to upset the next.
For one child, puppets, clowns, face painting and fancy dress might be a dream, while for others it's complete nightmare.
This dad learned the hard way how little his toddler liked shadow puppets.
On a sunny day, he filmed his toddler walking along the pavement outside.
Realising his shadow was in the shot, the dad decided to play with his daughter by creating a shadow crocodile with his hand, slowly coming towards her.
Big mistake.
The dad quickly stops and scoops his daughter up for a cuddle: "Come here, I got you, I got you" he says.
