What can you do to help your baby achieve all the important developmental milestones? Find out how a baby develops at 37 weeks.

A 37-week-old Baby’s Development

A baby grows tremendously in the first year of his life, and it is very common for a baby to experience growth spurts around 36 weeks. A baby boy weighs around 19 pounds and a baby girl weighs around 18 pounds around this age. According to the World Health Organisation, a baby boy at 37 weeks may reach approximately 28 inches in height and a baby girl of the same age may be able to attain about 27 inches of height. On an average, babies may gain approximately 3 to 5 ounces of weight and approximately 0.5 inches of height in the ninth month of their birth. Each baby grows at a different pace, and if your baby is somewhat close to these parameters, he may be doing just fine.

  • Your baby may be able to stand on his own by holding a chair, couch, or any other support.

You may see a major change in your how your baby’s food schedules and habits. He may become more independent around this age and may want to hold his feeding bottle or sippy cup on his own. On an average, your baby may be requiring around 700 to 900 calories in a day, and half of these calories he should get from breastfeeding, which means your baby, may need roughly 700 millilitres of milk on a daily basis. This may be just the right age for your baby to make the transition from a bottle to a sipper cup. Though it is normal for babies to show resistance, you can begin by offering water in a cup and gradually replace it with milk. Also, at this stage you should offer food first, followed by breast milk or formula. He should take three meals and two small snacks in a day. You can start giving a variety of foods to him such as sweet potato, bananas, apples, avocado, tofu etc. In order to determine whether your baby is eating or feeding well, keep a tab on his wet and soiled diapers. Also, monitor his weight to see if he is getting proper nutrition.

A baby’s sleeping pattern worries parents the most. The good news is that your baby may sleep for 14 to 15 hours a day by this age. This is divided into two parts, night-sleep of approximately 10 to 12 hours and one or two day-naps of 1 to 2 hours each. It is seen that most babies (approximately 70%) sleep uninterrupted for up to 8 to 12 hours at night by this age. He may not sleep peacefully in case he is unwell because of growth spurts or simply because of teething woes. However, if your baby is not sleeping at night or giving you trouble as far as his sleep is concerned, you can try sleep-training. This is because at this age your baby may be all set to be sleep-trained. You can make a sleep routine for him like massaging, bathing, singing lullabies etc. to give a clue to your baby that it is bedtime. It is okay if your baby experiences temporary sleep issues, he will get over that soon.

A 37-week-old Baby’s Care Tips

Here are some tips that you can follow to take care of your 37-week-old baby.

  • Brush your baby’s teeth using fluoride toothpaste. You can teach him to spit it out too.
  • You can buy a rear-facing car seat for your baby. It is a good idea to opt for a convertible seat so that it can be used later.
  • You should baby-proof your apartment because your baby may crawl by now and he may reach to all the places that are not safe for him.
  • Keep smaller objects out of reach as babies have a weird habit of putting everything in their mouths.
  • Keep all kinds of medicines out of bounds.
  • If you have stairs at home, secure that area too by placing a gate.
  • You can involve your baby in activities that enhance his motor, communication, cognitive and other skills.

Tests and Vaccinations

A healthy baby is a happy baby, and this is why you should never miss the appointment with your baby’s paediatrician. On your visit, your doctor may check your baby’s weight and height and would do other physical examination to establish that your munchkin is making the expected physical progress or not. Here are some tests and vaccinations that your doctor may recommend include the following:

1. Blood Tests

Your physician may suggest a blood test to establish any symptoms of anaemia in your baby. This is because it is very common for babies to become anaemic around this age because the mother’s milk lacks iron and thus the baby needs to rely on other sources of food to compensate for this requirement. If your baby is a fussy eater, there are chances that he may have lower levels of iron in his blood. Also, the tests may be conducted to establish any symptoms of lead poisoning.

2. Vaccinations

If your baby has been given his third shot of Hepatitis B at 6 months, then this may be the right time to administer the shot.

Games and Activities

Here are some games and activities that will keep your baby engrossed and help him develop his skills:

  • You could hide a squeaky toy under a blanket or behind you and let your baby look for it. This develops object permanence in him.
  • You can play peek-a-boo with your baby. Hide behind a curtain or door and let your baby find you.
  • Give a box full of toys of various shapes, sizes, and texture. Let your baby explore the contents of the box.
  • Take a big ball, roll it towards your baby and ask your baby to roll it back towards you.

When to Consult a Doctor

Here are some issues that may evoke concern in parents and may require a doctor’s consultation:

  • If your baby is unable to sit using other props.
  • If your baby does not lay pressure or put weight on his legs when you make him stand.
  • If your baby does not babble words like papa, dada, mama etc.
  • If your baby does not react or respond when you call his name.
  • If your baby does not recognise familiar objects or people.
  • If your baby is not able to hold or pass any object.

If any such developmental delays are observed, you may like to seek your doctor’s advice.

Your baby is likely to turn into a little explorer around this age; we suggest that you let him explore meanwhile keeping a close eye on him. Be there for him and let him turn into an independent and confident child.
