Someone from social services/the police seriously needs to sit her down and have a conversation with her about safe guarding and child protection. Perhaps even do it as a promotional exercise/bit of PR and share the info with her fans. Stacey Dooley did a Q&A thing with MIND the mental health charity answering questions on her stories after her psych ward documentary aired.
(Not saying the social need to get involved and open a case for The Hinches at all, merely that there should be some serious education/PR exercise about consent and keeping your kids safe online when they aren't even old enough to have their own accounts!)
I know Stacey Solomon puts her kids out there, as is her choice. But I'd ask serious questions/be really miffed if one of my friends put a picture of my kids (if I had any) on their grid for likes. I wouldn't do it to any of my friends. But if I did it'd be subtle, probably a group shot including adults and be posted on the day it happened not a week after we pretended to meet up (and tattle caught my voice the week before that in my friends garden
)
