A woman has been charged with child neglect after a baby died in “unexplained” circumstances four months ago.
Two-month-old Kevin Chen died at a house in Oxford, North Canterbury - about 70km northwest of Christchurch - on August 5.
Police originally treated the sudden death as “unexplained”.
A woman has now been charged with ill-treatment or neglect of a child under 18 years of age and another charge.
She is expected to appear at Christchurch District Court this afternoon.
