The driver wanted to help them but unfortunately, the Milo brand in the van was not ready yet but he gave them several locations where they can most likely find a van selling the beverage.

Doting husband Azmer said: ‘’My pregnant wife had cravings for the Milo van drink so when my parents bumped into one on the road, they chased after the vehicle.’’

Azmer said that his wife drinks Milo everyday and has drunk every kind of Milo available except for the one they sell in the van.

Natasya has been pregnant for eight months and has been craving the drink since her second month of pregnancy.
