I don’t think they’ll be removed at birth or anything like that if she makes it to term and he doesn’t do anything dodgy to reoffendSocial will get involved if they’re not already still involved because she’s previously had her kids removed. Tbf her 3 kids are probably on child in need plans.
They’ll def do a pre birth assessment and if there’s concerns they’ll put the babies on CIN plans before they’re born and carry out another parenting assessment once they are here. Social don’t play about people like them
but you’re right they’ll deffo be involved whether she knows it or not.
