Weaning

Hi all, my boy has just turned one and I would like to switch from breast milk to cows milk. Any advice/experience needed. He is eating solids well (not a huge amount) and still breastfeeds at least 4 times in 24 hours. I want to make sure he still gets enough milk and I would like to give him cows milk so please do not give advice that it is not necessary (which I have been getting). I respect everyone’s preferences for their baby and mine is to give him cows milk. Thanks in advance!!
