I don't like packaged milk for my 4 yr old kid. Can anyone recommend a fresh dairy milk vendor in SG?

My dad gets his fresh cow's milk from Viknesh Dairy Farm Pte Ltd. It costs 6SGD for 1 litre of milk. There is a minimum order of 5 litres for free delivery. 6 Lim Chu Kang Road, Lane 8A, Tel: 93805495
