Exactly. It's Julie who is putting her kids up on social media to her 148k followers plus any one who goes and looks at her public page. She is not thinking of her kids at all. People will comment whether its right or not. But it should be Julie thinking about her kids wellbeing not randomers on the internet.
In a few years her kids and their friends will all have phones and be able to get old photos and stories of her kids and know the ins andbouts of their parents relationship, how Fionn hated having his hair cut, that she ignored a broken bone etc etc. As kids they will grow to become embarrassed of their parents anyway but imagine most of your life being online and there for everyone to see.
