I look after my niece who has just turned 12 months old. Her mum doesn't believe she should be having cows milk and has put her onto a toddler formula. The days I have her she has 2 bottles as she eats breakfast, morning tea, lunch and afternoon tea. Her parents have now told me that they want her to have 4 bottles a day because that what the tin says but they don't seem to understand that the formula is just a food supplement. So my question is how many bottles should she be having in a day?
