Introduced milk

Had anyone tried giving their baby milk yet? My doctor told us it was okay and it doesn’t replace any breast milk sessions I just give him some once a day to get him used to it, usually with breakfast and watered down. I tried unsweetened almond milk and I think he liked it but would never finish it but I just got oat milk yesterday and he loves it!! I think that’s gonna be the one to buy him. Anyone else introduce milk to their baby? (My baby is over 11 months old)
