The quick answer is that you can continue as long as for and your baby are happy to do so. That could be when he is a year old or later but there is no need to stop breastfeeding until you are both ready to stop.
Most women have an idea of when they want to stop breastfeeding before their baby arrives and in the UK the expert advice is that, if possible, breastfeeding your baby exclusively for their first six months is the best choice.
Globally breastfeeding continues for a lot longer, in some cases for over 2 years.
What is your life like?
Your decision is your own to make and a lot depends on your personal circumstances as well as how you feel about breastfeeding. Even when your baby starts on solid food it is still fine to continue to breastfeed if you want to.
The level of support you have plays a key role; it is easier to continue to breastfeed if your partner, family and friends are supportive of your decision.
Sometimes this is not the case and many moms feel pressure to stop breastfeeding at a certain point. If this happens to you be sure to remember that this is your decision, and yours alone.
In the early days, you may feel like you are constantly feeding your baby and most moms find this first month pretty tough. However, those that stick with it are ultimately glad they did and the baby will settle down and cut back on the number of feeds as she grows.
Other mothers and friends who are breastfeeding can be a great source of support during this time.
If you are returning to work you can still continue to breastfeed although it takes a little organization and planning. Expressing breast milk and including supplementary bottle feeding works well for many women who are unavailable to breastfeed during the day.
Maintaining the evening breastfeed helps them keep that close bond and offer comfort to their child after a day of separation.
