As every baby's taste is different ( not counting allergies and such), have you try contacting the manufacturers ( email, phone, or signing up on their websites) so they will you free samples? I know that Enfamil ( formerly Enfalac), Simalac and Nestle/Carnation all gave me free samples when I visited their websites. Also keep in mind that by 12 months, you can introduce whole milk to a baby. HTH.
