Redditors recommended books that he could read to understand his niece’s experience of puberty, while others explained how to have an open conversation with her so she knows that he’s comfortable getting her whatever she needs.

Some suggested ways he could make her feel more confident and secure, like getting her a subscription to her favourite teen magazine and making sure that he never, ever cuts her hair himself.

Above all else, they suggested that he reach out to the mothers of his niece’s schoolmates.

“We have an amazing dad who worked hard to bring us up right, but I also have to give credit to our friend's mother for stepping up in that way,” wrote Patellabone. “Our friend's mother (who was also a close family friend) took us under her wing and gave us all of the uncomfortable talks.”

Another said: “[You have] gotta step up here and be BEST friends with multiple mothers in your daughter’s school.

“Essentially what this advice boils down to is to look for the helpers. They’re everywhere.”
