While all babies may grow at a different rate, the following indicates the average for boys and girls 7 to 9 months of age:
Weight: average gain of 0.5-1 pound each month; two times the birthweight by 4 to 5 months and three times the birthweight by 1 year
Height: average growth of about ½ inch each month
Head size: average growth of about ¼ inch each month
Babies’ growth begins to slow as the first birthday approaches. Your doctor has measured your baby’s weight, length, and head size (circumference) since birth and put them on a growth chart. This is where to look first if you have questions about your baby’s growth.
When you look at the growth chart with the doctor, compare your baby’s growth with his or her own growth pattern, not with the growth of other babies. As long as your baby’s growth is steady, there’s usually no reason to worry.
If you’re concerned about your baby’s weight or growth, talk with your doctor, who might ask:
Has your baby been sick? A couple days of not eating, especially if combined with vomiting or diarrhea, can lead to weight loss. The weight will come back when your little one feels better.
Is your baby on the move? Crawling, cruising, and walking will burn calories, so weight gain might be less with this new mobility.
Is your baby more interested in playing peek-a-boo or dropping the spoon on the floor than eating? The world is a fascinating place, and your baby is learning new things every day. Try not to distract your baby during mealtime. Also watch for signs that your little one has eaten enough.
Are you introducing the right kinds of foods? As your baby gets better at eating, pay more attention to the texture and types of foods you serve. If your child isn’t interested in puréed baby foods, try soft table foods and finger foods that are safe and fun.
Is your baby drinking enough breastmilk or formula still? Liquid volumes decrease as solid food volumes increase. However, it is important your baby continues to drink 20-28 ounces of breastmilk or formula a day to have enough calories to grow.
