Your Growing Baby

Talking Up a Storm

By this stage your almost-toddler is likely chatting up a storm. That's not to say he's necessarily uttering actual words, but you'll hear a distinctly conversation-like pattern to the way he talks, as if his nonsensical ramblings were an actual dialogue. For instance, the inflection of his voice will go up and down to indicate sentences and questions, and he might chatter for minutes at a time, as if he's earnestly trying to tell you something. Even if you don't understand one word, you can encourage your baby's first-word efforts by responding as if you understood everything he said: "Really, honey? Wow, that's so interesting! And then what happened?" Once in a while you might even hear a real word or two thrown in there.

On the Move

Physically, your baby might be taking one or two steps on his own by now, but if he's still perfectly happy sitting or crawling and hasn't shown any interest in pulling himself up yet, it's okay. Not all babies develop on the same timeline. Chances are, he's just proceeding at his own measured pace—and that might be a good match to his personality. Cautious babies sometimes acquire motor skills more slowly, only attempting new moves when they're sure of their movements and less likely to hurt themselves—by, say, falling backward when they finally do stand. Or they might prefer to master an entire process—such as pulling up, balancing, then gently sitting down again—before adding it to their everyday repertoire. If you're concerned, have your pediatrician evaluate him, if only to reassure you that you shouldn't count a late bloomer out.

Health and Safety Info

Allergies 101

Watery eyes, sneezing, stuffy or runny nose: It might be a run-of-the-mill cold, but it could be allergies. Since the symptoms are much the same, it can be tough to tell the difference, but here are some ways to single out allergies:

  • If you have a family history of allergies, since that makes your baby prone to developing them himself.
  • If he has other health issues related to allergies, such as eczema or asthma.
  • If he's allergic to other things, such as peanuts or penicillin. Environmental allergies to pollen or mold are a natural follow-on and could be what's making him sneeze.
  • If his runny nose is a constant, thin drip, rather than a cloudy nasal discharge.
  • If symptoms such as watery, itchy eyes and a runny nose last more than two weeks, or if it seems like your baby's just never going to shake them.

While the latest guidelines from the American Academy of Pediatrics advise against giving babies under 2 over-the-counter cough and cold remedies—they're not proven to help relieve symptoms and in rare cases might even be dangerous—there are some baby-safe allergy medications available, such as liquid antihistamines. If you suspect allergies, talk to your pediatrician about getting them properly IDed so you can start soothing your baby.


Get Ready for the 1st Birthday Party

Just a few more weeks till baby's first birthday—and whatever celebration you're planning to go with it. Before you go all out, remind yourself that your baby won't remember one bit of this day a year (or, face it, two months) from now. In fact, an all-out party, complete with clowns and balloons, might be overwhelming. To save on stress, consider simply inviting grandparents over for a low-key get-together after naptime. With a few presents to open, a few streamers to admire, and a piece of frosted cake to squish between his fingers while Dad takes tons of photos, it'll feel festive without freaking your baby out.

But if you have your heart set on a bigger party, don't shy away. After all, this is your special day as much as your baby's, and a blowout bash is a surefire way to commemorate how much your whole family has grown and changed this year. Starting to prep now will minimize stress and save last-minute running around so you can truly enjoy your day together. Here's what to do with one month to go:

  • Pick a theme—a color, a pattern, a cartoon character—and scoop up the decorations and favors.
  • Plan the menu. Keep it simple and baby-friendly (no hot dogs, popcorn, or other choking hazards), although you can have some more gourmet nibbles on hand for the grown-ups.
  • Send out invites. Before you do, think carefully about the party's timing. Scheduling the festivities for late in the morning or late in the afternoon, after naptime, and limiting the party to two hours offers your best shot at avoiding a midparty meltdown.
