Your baby can now focus for longer periods and its attention span has also improved. This means that your baby will now be following sounds and moving objects more closely.

  • Movement- 

Gone are the days when your baby could only make startle or jerky movements. Smoother movements are also spotted.

  • Self soother- 

By now, your baby has likely found its thumb and the joys of thumb sucking. Don’t be surprised to find that your baby has voluntarily brought its fist to its mouth and has started sucking its thumb on its own just to soothe herself.

  • Music lover- 

The improvement in hearing and greater alertness has turned your baby into a music lover. You will notice that your baby will respond differently to different types of music. Now would be a great opportunity for you to understand your baby’s personality.

The improvement in your baby’s memory means that it is both a boon and a bane for you as a parent.

Gone are the days when you could entertain your baby with the same object time and again. With improved memory, your baby will get bored with the same things and you will need to find new ways to keep your baby entertained. 

If you don’t feed your baby’s curiosity from now, you will notice that your baby will get fussy and start crying just to get your attention. Try going out with your baby as you will see that your baby will love to explore new places and people. However, remember that you still need to keep your baby in the stroller while in public. If this is your second baby, ensure that you know the things to do with your first child.

What is some basic baby care knowledge that every new parent should have?

  • Feeding-

If your baby is going to have a growth spurt during this week; you will notice that your baby will be hungrier. You will still need to continue feeding your baby on demand. The breastfeeding sessions will continue up to 20 minutes. If you notice that your baby is nearing the growth spurt then it will be less hungry than the previous week.

If your baby’s nighttime sleeping is improving then your baby will require lesser night feeds and will tend to do cluster feeding.

  • Sleeping-

Your baby will start to develop a sleeping pattern. Your baby will start sleeping less during the daytime and will be sleeping for longer stretches during the night. You will have a more alert and interactive baby and your baby will be sleeping around for 14 hours each day.

Make your baby develop a consistent and efficient sleeping pattern by helping it understand the difference between night time and day time sleeping. Introduce a story-time, and make the story-time extremely fun for your baby. 

  • Bowel movement- 

It is normal for babies to have lesser wet diapers from this stage onwards. If you are exclusively breastfeeding then your baby may have even lesser bowel movements.

A lot of babies only have one bowel movement each day and can even have no bowel movements for or a few days. As long as you don’t notice any signs of constipation, it is completely normal.

When to call the doctor?

  • If your baby still can’t hold its head up for a few seconds while lying on tummy.
  • If your baby doesn’t smile at all.
  • If your baby has no response to loud noises.
  • Visual following is absent.

  • Start introducing the bottle to your baby. This will help you to transition to work easily as you won’t be constantly worried about your baby’s feeding.
  • Get your childcare in order. You need someone dependable looking after your baby when you go back to work. This will help ease the separation anxiety that most working mothers face while going back to work.
  • Take some time out of your busy schedule for self-care. Take some time off and spend it with your spouse, partners, other children, or friends. This will make the time you spend with your infant even more special.
  • Get medical help and emotional support to get you through postpartum depression and anxiety.
