I'll find some links for you. His family friends spoke about him being very difficult as a child. There was even a book written about him. I will link it below.

Nick Reiner’s Childhood Tantrums Were Depicted in an Illustrated Book About Yoga
The family instructor tried to make the best of his behavioral issues by channeling them into 'A Chair in the Air.'
Published in 2005,
A Chair in the Air was an attempt by yoga instructor Alanna Zabel at processing her experiences working for the family in the early 2000s, when Nick would regularly interrupt the private classes with screaming outbursts that could last 20 minutes or longer,
according to the Daily Mail.
The 32-year-old's strained relationship with his parents has been no secret in Hollywood, with his father even making a film with his son about the challenges they faced due to Nick's drug addiction.

Troubled truth about 'little Nicky': Rob Reiner's friends reveal son's lifetime of red flags... as he's arrested over violent murders

Rob and Michele Reiner's son Nick was a deeply troubled child who needed physical restraint for his rages from a young age, according to a family friend who has known the 32-year-old all his life.
But the family friend told the Daily Mail that Nick's issues began well before his teenage years, and sadly suggested that Reiner, 78, and Michele, 70, 'babied' their son — to the frustration of his siblings Romy, 27, and Jake, 34.
'A lot of their fights had to do with him just doing something self-destructive, and fighting back when they tried to help him,' the friend said. 'It did get physical sometimes — I'm not talking punches, but restraining him.
'I was over there, it must have been early 2000s because he was about 11, and he was throwing the biggest tantrum, and Reiner just had him in a bear hug to restrain him.
'The tantrum was over nothing, but he had so much anger in his eyes. It was terrifying really. And this happened a lot, and he never outgrew it. He had tantrums in his 20s.'
And Rob and Michele were so protective of all their kids, but especially Nick. He was the one who gave them the most trouble. There were a lot of sleepless nights because of him. The drug use, the mental spirals. He was unwell a lot of the time, and they were doing whatever they could to hold it together for him. To anchor him. He just had so many problems; he was so troubled. And they loved him dearly.'
