We have a situation where a third party has made an accusation of domestic violence, nobody has yet been convicted, the father denies it, and CPS takes one day to take the baby away from its mother? I would hope it would take more than an accusation from a potentially disgruntled ex-partner to cause this trauma on a mother and a baby.
