When you exercise, your body releases lactic acid, this lactic
acid is then found in your breast milk. Some babies have been found to
be less enthusiastic about drinking after a mother has exercised; this is due
to the lactic acid changing the taste of the milk, giving it a bitter or sour flavor.
There are no harmful effects when a baby drinks the lactic acid. Exercise will also never have an impact on the quality or quantity of breast milk. Some studies have found that many mothers experience a slight increase in breast milk supply when they exercise regularly.
What are the Benefits of Exercise, if you are Breastfeeding?
Losing the pregnancy weight is easier with exercise.
The mother feels happier and is at a decreased risk of experiencing PPD (postpartum depression).
Exercise increases bone density, which is sometimes a problem
for mothers who breastfeed, and who might lose a lot of their calcium stores.
Postpartum exercise accelerates post natal recovery.
Exercise usually results in more energy during the day and sleeping better at night.
Start slowly. Do not try to lose the postpartum weight too quickly.
Wear a good sports bra that will give extra support.
If your baby does seem to dislike the breast milk after exercise, try exercising immediately after a breastfeeding session, this way the lactic acid that is formed during exercise, will be gone by the time you need to breastfeed again. If you are worried about the aerobic exercise, you can find a group of ladies that take walks with their strollers or you can consider Yoga as an alternative form of exercise. If you happen to have a treadmill at home, this can be an easy way to take a good walk no matter what time of day or night.
