Toddler Caleb Skinner is slowly improving but doctors have told his parents he won't fully recover from the injuries he received when he was assaulted.
The 2-year-old was assaulted at his George St home on March 3, allegedly by a man known to his mother, Joanne Smith.
Caleb was resuscitated by ambulance staff and taken to Wairarapa Hospital with serious head injuries where he was stabilised, put into an induced coma and flown to Starship Hospital for further treatment.
Caleb has slowly been brought out of the coma by doctors but it is early days yet.
His dad, Daryll Skinner, said doctors were unable to say how much brain damage Caleb had sustained or how it could affect him long term.
