My LO has just turned 11 months - we have literally overnight switched out 2 of his 3 bottles for cows milk! I heat it in the microwave for 30 seconds then he drinks it out of his bottle no issues 😇
My little one turned 11 months last Thursday and we transitioned straight away with one of his bottles. I would try with a straight swap with one bottle first and see how they get on as he didn’t even seem to notice! I also heat in the microwave for about 30 seconds in a bottle😊
Can either mix them at 1st or go straight to cows milk x
