The longer you breastfeed for the better but it's an individual choice for each mum-baby pair. Some mums are happy to breastfeed for more than a year, whereas other mums introduce formula sometime before 12 months. Experts recommend that you exclusively breastfeed till around 6 months when solid foods are introduced and then continue to breastfeed up to a year or longer if you can, but it depends on your individual situation. It's important not to compare yourself with other mums and feel guilty for not making exactly the same decisions, do what's right for you and your baby.
