Lay baby face-down on your shins, facing you while you lie on your back. Hold onto baby with your hands to keep her secure. Keeping your knees bent and your feet off the floor, engage your abdominal muscles by pulling your belly button in towards your spine. Keep a space between your chin and chest (looking diagonal towards the ceiling).
EXHALE: Lift from your hips, pulling your knees towards your chest, focusing on your abdominals. INHALE: Slowly lower hips and legs back down to the starting position to complete one rep. Aim for 1-3 sets of 10-15 repetitions.
Safety should be your main concern, for you and the baby. Make sure that baby is totally secure in all movements. If any exercise is uncomfortable or too strenuous with baby, try it without baby first. This is a very slow, small and deliberate movement. Be careful not to use momentum. Try to keep the motion controlled by your abs.
