The sequence of electrical activity within the heart is displayed in the diagrams above and occurs as follows: As the SA node fires, each electrical impulse travels through the right and left atrium. This electrical activity causes the two upper chambers of the heart to contract. This electrical activity and can be recorded from the surface of the body as a P wave on the patient's EKG or ECG (electrocardiogram). The electrical impulse then moves to an area known as the AV (atrio-ventricular) node. This node sits just above the ventricles. Here, the electrical impulse is held up for a brief period. This delay allows the right and left atrium to continue emptying it's blood contents into the two ventricles.
However, a one year old still needs about 24 ounces of whole milk per day. Getting them to like the whole milk prior to transitioning to a cup has helped in my experience. Not all children will need this gradual transition with the bottle, but some will most certainly benefit from it.
Before their first birthday, babies still need the nutrients in breast milk or formula. But at 1 year old, your baby can try whole cow's milk. Why not skim or 2%? Because babies need the fat in whole milk for normal growth and brain development during the busy early toddler period. You can transition your baby from formula to whole milk by beginning to replace bottles of formula with bottles â or sippy cups â of milk. By 1 year old, your baby should be eating a variety of other foods and only 2-3 cups (480-720 milliliters) of milk per day. If your baby was put on a soy or hypoallergenic formula because of a milk allergy, talk to your doctor before introducing milk.
