My eldest was born very premature.. He still had a bottle at 3yrs of age! My younger 3 were born overdue, and breasted until 12-13mths each… They started on cows milk just after their first birthdays, and only ever had a bottle at night, they had sipper cups during the day! They were used to drinking from a cup because they drank water, or freshly squeezed juice from their cups while i still breastfed them. The bottle only lasted a few months (6mths at max), and then they didn’t want it anymore, they just wanted their cup.
