I am a dum dum.... Pls help with this milk question for my nine month old!!!!!!?

TO GET HIS DIGESTIVE SYSTEM USE TO IT.... YOU SHOULD MIX IT.... 50/50 IT..... I STARTED MY BABY ON THAT @9 MONTHS..... BUT NOT WITH WHOLE MILK BC APPARENTLY SHE CANT DRINK WHOLE MILK BUT SHE CAN DRINK 2% MILK...... && ALSO TRY HIM ON THE PEDIASURES..... THOSE ARE EXPENSIVE ($9 FOR A 6 PACK) BUT THEY REALLY SIT WELL WITH BABY'S TUMMY!
