Your Growing Baby

So Many Milestones

For your baby, this first year has brought more changes in the shortest time span than she'll ever experience again, and the last month has been especially busy. Physically, your baby is hitting milestones galore: cruising by grabbing into furniture, walking when you hold her hands, bringing herself to a standing position by flexing her knees and pushing herself off the floor with her hands, and sitting down solo. Sometimes her body moves faster than she wants it to, which might explain why your little walker sometimes prefers to crawl.

On average, at the year mark babies can say "Mama" and "Dada" (or something like that), along with two to eight other words, often "no" or "bye-bye." Her sentences at this point are usually just babbled, but you'll catch her intention from her up-and-down intonation—and she'll love it when you respond in kind.

She also has a fascinating personality now, complete with a full range of emotions that she expresses freely (and recognizes in others). While your toddler still has a little stranger anxiety and prefers certain familiar faces (such as yours!), she's often affectionate and funny, eager to play with you and others, and happy to grow into the stages ahead.

Baby's Expanding Menu

Just when you thought that feeding would get easier—after all, your 1-year-old can pick up her own food, drink from her own sippy cup, even help select her own snacks—suddenly it seems like she's not eating much at all. Seeing a change in eating habits—and a slow-down in both weight and height gain—at the year mark can be disconcerting, but it's totally normal. Here's a rundown of how much your 12-month-old should be eating each day:

  • 3 ounces of grains. That's five whole wheat crackers, a slice of bread, 1/2 cup of pasta, and 1/2 cup of cereal.
  • 1 cup of veggies. Try cooked carrots, mashed potatoes, diced fresh tomatoes, or canned corn—or hide spinach in favorite foods, such as pasta or even brownies.
  • 1 cup of fruits. Strawberries, applesauce, and canned peaches all count, as does juice; but try to limit juice intake since it tends to offer more sugar than fiber.
  • 2 cups dairy. Think milk, yogurt, pudding, or cheese. A few slices of cheese (1-1/2 ounces) equal 1 cup of milk.
  • 2 ounces of protein. That could be 1/4 cup of cooked beans and an egg, or 2 tablespoons of lean meat and 1 tablespoon of peanut butter.

Measure the servings out for a few days, and you might be surprised by how little food your kiddo actually needs. So stop worrying and follow your little one's cues at mealtime.


Celebrate Your Baby's 1st Year

In some ways it feels like the time flew by this last year; in others it seems like the longest year of your life. After all, a little more than a year ago you hadn't even met the little person who has changed your day-to-day so dramatically. Now you can't even imagine life without her.

So while you're all geared up to celebrate your baby's 1st birthday, take a minute to celebrate your first year as a mom. After all, you've certainly mastered a few interesting milestones:

  • Getting up in the middle of the night to feed, burp, and rock a fussy baby—and only nodding off three times while you do it
  • Changing the worst of diapers without flinching
  • Nursing your baby anytime, anywhere, no embarrassment
  • Building up impressive biceps from hauling infant carriers and holding your baby for hours on end
  • Handling ear infections, fevers, cuts, scrapes, bruises, rashes, screaming, and crying with aplomb
  • Offering kisses, hugs, squeezes, and cuddles on demand
  • Feeling more love than you ever thought possible

No matter what you expected going into motherhood, at the 1-year mark you probably feel like a totally different person. And no wonder: You've successfully cared for your baby for an entire year, making her an integral part of your life and very possibly the center of your world. And you survived! Congratulations, and happy motherhood anniversary!
