If like you say the women thought she was lost it seems uncanny that as soon as the mum moved away to get a drink for her child .the other women made an attempt to take the child out of the play are.so she must have been watching them. Also as there were other parents present with their children. The women did ot approach them to ask if the child was theirs.also the child said she said ile get you an ice cream .no if you think a young child is lost you look for help or ring the police.
