Formula to whole milk

Bri

When did you transition Formula to whole milk for your little one .

My son has his Appointment tomorrow for his 9 month check up and will be asking & also read It’s best to wait till child is One , but just wanting to see when did y’all start and all .

I also am starting to transition from bottle to Sippy cup !

( I done forgot since it’s been almost 5 years , mom of 3 lol )
