How to take care of your baby? – Baby Week 12

Reading aloud is the best way to help baby develop. Hearing your voice and familiarizing your baby with the rhythm of the language are also great ways for a faster development. Changing the tone, accent, and even singing to your baby makes your interaction with your baby more fun. If your baby overheads or looks uninterested, take a break. You must always be aware of your baby’s state and react appropriately.

There are many good books that are perfect for reading to your baby, choose books with lots of big pictures, bright colors and simple characters, so that they can be described again and again. When choosing a book, you don’t have to care about the target age of for the book. A book suitable for older children to read, as long as the picture is clear, bright and colorful, will still attract baby’s attention.

You can create a positive atmosphere for your 12 week old baby by:

  • Hugging your baby
  • Interacting with your baby
  • Talking to your baby
  • Relaxing your baby with gameplay
  • Giving your baby a separate space
  • Letting your baby do what they like to do
  • Doing the right thing to do at the right time

Health information for your baby – Baby Week 11

  • Weight, height, head circumference, and post-birth development.
  • Medical examination, including examination of previous problems.
  • Guidance for feeding, sleep, growth and safety in the coming months.
  • Answer your questions, for example: What happens to your baby after vaccination? What should I do?What happens to your baby? Call a doctor?
  • You should also be aware of other health conditions, or work problems, such as changes in feeding and family conditions after returning to work within the last month.
  • Record the information and guidance provided by your doctor and write down all important information in your baby’s health record, such as weight, height, head circumference, birthmark, vaccination, disease, medication and test results, etc.

The needs and development of your baby – Baby Week 11

You should know the following:

Flat head

If the baby’s head is flat, it may be because of laying down on the sane position for too long. When babies are born, the skeleton is very soft and highly elastic, so if you sleep too long at night, the back of your head can easily become flat. But do not worry too much, no matter how flat the head is, as long as the baby starts to learn to sit, it will return to normal.

To make sure everything works, you should take your baby to a pediatric neurologist or cranial specialist to confirm the severity and whether treatment is required. If not serious, your doctor may teach you some home treatments, such as having your baby lay down to strengthen the neck muscles (the baby must be awake and supervised by the parent).

Hair loss

If your baby has no serious health problems, hair loss or baldness caused by posture is not a big problem. Hair in these areas can easily fall off as baby tends to keep the head in the same position and constantly rubbing the mattress, or the edges of the crib. As long as your baby grows up healthily, hair loss will stop.

However, it is difficult to predict when the hair will grow back, and most children will have hair before the age of 1. After hair loss, hair growth will become different, some babies will grow their hair back soon after hair loss, others will take a little more time.The new hair color and hair texture may differ significantly from the time of birth.


Hernia is usually obtained by adults who often lift heavy objects, but in fact, even children who do not carry heavy objects may get hernia.Hernia often occurs in infants, especially boys, premature babies or twins. If your child has a hernia, you can find early signs such as lumps in the folds between the thighs and abdomen (ratchies), especially when the baby is crying or restless, which are usually quiet in the baby, the intestines may slide into the scrotum, causing it to bulge.In short, the hernia does not bring any discomfort to the baby, as long as it is properly treated, it will not be dangerous.

However, if you find a lump in the groin or scrotum, take your baby to a doctor as soon as possible. If your doctor diagnoses a hernia, some treatment is usually recommended. In some cases, the doctor might decide to do surgery. Hernia surgery is very simple, has a high success rate and can be discharged quickly.

The recurrence of hernia after the procedure is rare. If a hernia is not treated, it may cause tissue falling into the groin tube, having it stuck in the muscle layer, and poor blood circulation may affect intestinal digestion.This can cause the baby to vomit, feel pain, and even panic. If you find your baby crying suddenly and seemingly in pain, vomiting, or being unable to bowel, bring him or her to the doctor immediately. If a familiar doctor is not present, head to the emergency room immediately. On the way to the emergency room, lift the lower body slightly and put an ice bag on the abdomen so that the intestines can shrink. Do not try to reset or massage the intestines with your hands.

Reminder for parents – Baby Week 11

You may be of particular interest to the following:

  • Development indicators can be used to compare the child’s development with the same age, to assess whether there is stunting. Keep in mind not to compare the child with other children or siblings, because this can only increase fear and disappointment.
  • Two perfectly normal babies have different development situations in different settings: one language may develop faster, speak earlier, speak more , and the other body develops faster, learn earlier or to roll earlier. At the age of 1, the difference is more pronounced, some climb and start walking at 15 months old, some do not climb yet, but stand up and walk at 10 months old.

Therefore, the evaluation between parents is subjective and not entirely accurate. Some parents may not even realize that the child’s crunching voice is beginning to learn to speak, while others have long discovered that the baby can say “Dad” too. And these examples again show that you shouldn’t compare your baby to other peoples’, and that makes no sense.
