Weeks 11 – 16

Baby’s Health and Well-Being

  • Some babies will be heading to the pediatrician for a monthly check-up, while other doctors skip the months that don’t require immunizations. If you do have an appointment scheduled, breathe a sigh of relief that your baby probably won’t have to endure any shots.
  • If you notice a sudden change in your baby’s bowel movements, look to the color and consistency rather than the frequency to determine if something is wrong. It’s normal for your baby to produce less waste as his or her digestive system matures, but if you notice watery or small, hard stools – especially if it looks greenish or bloody – then call your doctor.
  • If you’re still in the midst of colic, take comfort in knowing that most cases subside around the three-month mark. If you’re still having trouble dealing with excessive, unexplainable crying, check back to our Colic Survival Tips.
  • Never ever shake your baby.
  • Preventing SIDS:
    • Although you might feel that your baby instinctively wants to sleep on his or her stomach, experts still warn that it’s safest for babies to be on their backs. Don’t worry; the baby will only have to sleep sunny side up for a few more months. The danger of tummy sleeping seems to diminish once he or she can sufficiently roll around. Since the American Academy of Pediatrics started their “Back to Sleep” campaign in 1994, SIDS-related deaths have decreased by 40 percent.
    • There are many products on the market claiming to position your baby in a way that prevents SIDS, but none are proven to actually work. Laying the baby flat on his or her back is the safest position. Sleep positioners are no longer recommended by the FDA for safe sleeping.
    • Moving the baby to the crib? Make sure the mattress is extra firm and free of any fluffy, loose bedding. If the baby has taken residence in your bed, do your best to clear away any pillows and comforters.
    • Instead of loose blankets, opt for sleeper blankets if the baby needs a little extra warmth. Don’t over-bundle, however, because overheating can be dangerous as well. If your baby is rolling now, it’s definitely time to get rid of the swaddle.
    • Ban anyone from smoking near the baby.
    • The best temperature for the baby’s room is between 61 and 67 degrees. If you need to cool down the room, don’t let an air conditioner blow directly on your baby and keep the bassinet or crib as far from the unit as possible.
    • Using a fan to circulate the air in your baby’s room is believed to reduce SIDS by 72 percent.
    • Although pacifiers are thought to reduce SIDS, if the baby hasn’t taken one by now then don’t even bother. Many experts encourage parents to nix the pacifier habit around three months anyway.
    • If you have an overwhelming, debilitating anxiety about SIDS, it could be triggered by postpartum depression and warrants professional help.


While it might be hard to determine when you should call the doctor and when you should wait it out, the following symptoms warrant a call to the doctor – and sometimes to emergency medical personnel – immediately:

  • Blue lips or skin.
  • Yellow eyes or skin.
  • Indications of dehydration, typically after vomiting or having diarrhea for an extended period of time:
    • Dark, concentrated, strong-smelling urine
    • Six hours or more without a wet diaper
    • Dry lips
    • Unusual lethargy
    • Sunken eyes and cold, splotchy hands and feet (which warrants an immediate trip to emergency room)
  • A temperature of 101 degrees or more. (Keep in mind that our bodies naturally have higher temperatures in the late evening and night.)
  • White patches in the baby’s mouth that won’t easily run off, usually indicating a contagious yeast infection called thrush.
  • Constant crying, refusal to eat and/or difficulty sleeping due to a large build-up of gas. You might need over-the-counter or prescription medication to break up the gas bubbles.
  • Repeated projectile vomiting, accompanied by choking or gagging while eating, apparent abdominal pain, and/or trouble sleeping and eating. The baby could have reflux.
  • Diarrhea and/or vomiting for over 24 hours.
  • Several refusals to eat in a row
  • Bloody stools
  • Vomit containing green bile, which could indicate an intestinal blockage
  • Bloody or smelly urine, irritability, crying during urination, and vomiting, which could be a urinary tract infection.
  • When the baby is constantly pulling at his or her ear while crying, especially if you see fluid draining from the ear
  • If your baby is having a hard time breathing (along with cold symptoms), this could be respiratory syncytial virus (RSV), which can cause a lung infection (pneumonia) or swollen, mucus-blocked airways (bronchiolitis) – both of which are extremely dangerous.
  • Vomiting repeatedly after a head injury, which could indicate a concussion.
  • Excessive sleepiness or any other drastic behavioral change.

    Hi Suzie. I have a 3 month old little girl who wasn’t on a set schedule and I felt like feeding / sleeping was all over the place. So I read the ‘tizzie hall save our sleep book’ which has wonderful advice on baby’s sleep cycles. I followed the suggested schedules for a few days in a row, making sure the schedule was the same but also being flexible. Now my little girl is into a great routine and sleeps through the night.
