A mother who took her one-year-old daughter from a foster family who were caring for the child is being sought over concerns for the baby's welfare.
West Midlands Police said they were concerned for missing child Lola Page after she was taken during a supervised visit in Willenhall in the West Midlands just before 1pm yesterday.
Mother Stacey Ball, 18, of Walsall Wood, is believed to have got into a dark-coloured car with her child which was then driven off, after leaving the address.
There have no sightings of either the child or Ms Ball since the pair went missing, police said.
A force spokesman said that at the time of her disappearance Lola was under the care of social services, and had been placed with a foster family.
Detective Chief Inspector Matt Markham, of West Midlands Police, said: "There haven't been any sightings of Stacey or Lola since they went missing and both police and the local authority are extremely worried about their welfare.
"Lola was in the care of social services at the time of her disappearance and we urgently need Stacey to make contact with us or anyone who may know their whereabouts."
Lola is described by police as white with short straight blonde hair and was wearing a white cardigan and blue polka dot dress when she was taken.
Ms Ball is described as white, of thin build and was wearing a long black wig, black leggings and a black and tan patterned dress when she left with her daughter.
The force has released a photograph of mother and daughter which was taken on the day they went missing.
Anyone with information is urged to call police on 101 or contact Crimestoppers anonymously on 0800 555 111.
