2 or 3 on same flight
I've had either 2 or 3 go around on the same flight. A 767 arriving from Stockholm, which was caused by a young child aged about 5-6, who refused to sit in her seat with seat belt on.
The Senior FA was remonstrating with the mother, who came across as pretty useless. The mother was claiming to the FA 'You clearly don't have children as you don't know how hard it is to get them to behave' to which the FA replied 'I've got 3 and if they behaved like yours, they'd be dead'
The pilot came out to have a discussion with the parents on landing.
I was in the same row as this, so seeing/hearing all this first hand, but it was a few years ago now.
We eventually landed with the parents physically restraining the now screaming child.
