The fact that FL left the UK is probably a large factor in why her child is safe- because of the distance she put between her child and her ex.
Presumably without the intervention and threat of removal by SS she would not have left the area she was living in and the child may have been at risk from ex?
I think many cases of removal actually come down to this- the failure to protect the children from others (frequently violent ex-partners, but not always). But why isn't there more help for families that are struggling? Why aren't there enough units for mothers and babies, in particular young mothers who having been through the care system who do not have a positive experience of parenting, or perhaps have never experienced life with a baby at all ( eg if all younger siblings removed at birth) and really need practical support?
Money of course, it's always money.
My authority is closing down mother and baby unit
there aren't even enough places now, let alone after they're closed.
Yet look how much a care placement in a residential unit costs- upwards from £2k a week! (because let's face it there just aren't enough foster carers, never will be and that situation will worsen as fewer and fewer adults can afford homes of a decent size to foster).
