Gradual weaning on to cows milk or not?

Following this one, I have no idea how to swap, when he drinks out of an open cup he has a sip then the rest he spits out 😅

I gave LO a bit of milk to try with a snack the other day and he seemes to love it. However im still skeptical that he wont get enough nutrients and vitamins on his own( i give about 6 different veg or fruit options a day but its whether or not its enough of each one for it to be nutricionally beneficial to him). Im swapping the morning bottle for cows milk and using a follow on stage 3 milk for bed time. Its probably the wrong thing to do but never mind

I’m doing same as I did 9 years ago with my eldest, straight swap to full fat cows milk at age 1 ☺️

I’m thinking about keeping the formula just for bed time bottle for the vitamins just for a while but not really sure yet. I’ll probably swap out one bottle to cows then after a while 2 bottles and gradually swap it n see how he goes
