After 1yo, milk become a supplement. It’s better you feed full lunch, and slowly wean them off milk. You wouldn’t want a case where the reject ur lunch and know there’s milk after that anyway.
I did that. my boy don't eat much as he's picky so I will give milk after 1-2hrs after each meal
Light lunch followed by milk is ok as they still require to drink milk at that stage
It is better if you can give your baby a balanced die with veg, meat or fish
