You still need to prove your identity, if we're going to take you seriously as Lou's Mum (there's a lot of snakes on here). I'll ask again though, cause I think you missed it:
My question to you is pretty simple - what do you think would cause Lou to be a better person, that would lead to her getting the children back? She already has support, from the state, from you, and from strangers on the internet. She seems to have hit "rock bottom" a few times - what's the missing puzzle piece?
(I would also love to know what she stole from you, and what led her to being estranged, but that's just me being nosy. And please, tell us about Carol)
