Pregnancy and lactation are quite compatible and continued breastfeeding helps the older child feel secure during a time of change.
During your pregnancy you and your toddler will have to accommodate some changes. Beginning about the fourth month of pregnancy your breast milk may decrease in volume and begin to change to colostrum. Your toddler may react to these changes or they may not.
If you decide to stop breastfeeding it is important for you and your toddler to find time together. This is a great time for other members of the family to take an increasing active role in the life of the toddler.
