Before starting your activity log be aware there's no single "standard" for the number of kicks to expect, but on average you should be able to detect at least 5 definite movements per hour in the last trimester. Babies sleep, and there may be times in the day when you feel little or no movement. That's why it's important to be aware of any changes in your baby's daily pattern. In time you'll get used to your baby's particular patterns.
The My Kicks Count chart will allow you to keep an accurate record that is foldable to fit in your billfold, and informative enough to be used by your physician. Bonus effects are, the process of using this chart is another method of helping you bond with your precious baby as well as become more familiar with their daily routine.
