No-one doubts she is not a good mother. I don't think it has ever been mentioned that she isn't.I actually quite like Lee and think her wee boy is cute, sometimes she seems a bit mad but who doesn't. Agree to some extent that kids shouldn't be posted on public accounts for goodness knows who to see! At the end of the day she seems like a good mum to me and at least she isn't like social mama aimee that posts videos of herself rambling to instagram about how she's enjoying self care time then says in the next story that her 3/4 y/o child has just pished herself so she can also have a bath at 10pm (which appears to be a regular occurrence).
La la loves to share every aspect of her life. And as a father I find that concern that a wee child can be used to engage your insta following.
But that is just my humble opinion.
