My DD went down to just 1 bottle (bedtime bottle of 250ml) from about 13 months. The MCHN let us know that her diet was really good and she was getting plenty of good stuff and calcium from her food so didn't really need the bottles anymore. Luckily DD was willing to give them up easily. For the bedtime bottle we started giving half formula and half cows milk and she is now happy to have just cows milk.
