At 12 months old Aidyn was having at least 3x 240ml bottles during the day, and sometimes even a 4th one during the night.
I switched him to Toddler formula at 12 months (s26) but then I didnt like the fact that it said you could mix it with milk OR water, and I didnt know how much to mix, so I went back to the normal Step 2 formula for a few more months.
Then I made the swtich to Heinz Nurture Toddler formula, which you just mix with water, and doesnt smell all vanilla-ish like the s26 did... it also doesnt seem to be as sticky/sugary.
At 2 years old he is now on 2x 180ml bottles.
