Still, there are at least a few clues. One sign that your child may be just about to sprout up is an increase in his appetite; another is too-small shoes. Kids grow from the bottom on up; after their feet grow, legs lengthen, hands get bigger, and then arms become longer. Some things to keep in mind while your child's going through a growth spurt:
* A baby may want the breast or bottle more often or take in more at feedings. Let him. And allow older kids to eat and drink more as well -- just make sure you offer a healthy variety of food, plus milk.
* After age 3, growth spurts can lead to growing pains. These leg aches tend to happen at night, especially after a day of lots of activity. Gentle stretching, plus a heating pad or a warm cloth, can help ease them.
