Regular milk

Amrita

Just wondering how you mamas are going to approach giving regular milk to your littles? My son will be 1 in less than a month on Aug 17. Was wondering if I should start slowly adding milk to his formula at 11 months so by the time he's 1 his digestive system is use to it? Or maybe just give him a bottle of regular milk when hes 1 and see how it goes? What are y'all thinking/ planning to do to transition to milk?
