Who says exercising can't be fun? Take it to a new level for both of you. Plop that tiny tot into a sling, put on some moving music and "boogie!"
A baby only has one way of communicating -- crying. Everything is incredibly new to them, every feeling, every experience. Sometimes, for a new parent, it can be very difficult to work out exactly what your baby is crying about.
Many parents ask if they should pick up their crying baby, concerned that they will spoil the baby if they do. My simple answer is "Yes, pick up and attend to your crying baby". By being responsive to her/his crying, you are letting your baby know that she/he is loved and cared for and that will give her/him security.
