Hi Rachael, my dd is also 14 months, she has 16oz of milk a day and yoghurts (she is mpi so we are slowly introducing dairy). So its 1 8oz bottle in the morn and 1 8oz bottle in the eve. As long as she has plenty of dairy products and 16-20oz of milk a day she is doing fine. If it is a little less that is ok, as you said she has plenty of dairy too.
