Your baby's 45-weeks after birth

Your 45-week-old baby is finally turning into a child who is more interested in eliciting reactions from the people around him. The little can now be able to drink out of their cup or hear and understand a big ‘NO’ out of you. However, on the other hand, parents must be cautious of the baby’s crying, being clingy, and crankiness but you can treat them with love as and when they grow with extra confidence and are independent enough.

Your baby’s sleep:

  • Babies at 45 weeks have quite a disturbed sleeping pattern, meaning the little one could spend more time drinking breast milk and might spend time infrequent feeding, also known as ‘breast sleeping’.
  • If you are in this situation, make sure to be supportive and ease any strain from the fixed position. You can switch your baby to the other side in the middle of the night to help you ease the position of your body for a night of better sleep.
  • The good news is that this period is only temporary as it is the baby’s developmental phase, and will return to the normal routine in a few days or a week, as per the need of the baby.

Your baby’s diet

  • Your 45-week old baby has almost completed a year, so you can start weaning your baby from breast milk, however, it is not a compulsion if you have the time. Breastfeeding can be done until 24 months as the toddlers gain more nutrition and immunity from breastfeeding.

  • Give your baby one feed when they wake up

  • Give the baby lunch and breastfeed as per their needs
  • A mid-afternoon feed just before their nap
  • Dinner and breastmilk
  • And last, at bedtime

You can also find a natural comforter for the babies to help take the baby bottle away from them, such as a pacifier. And, replace the breast milk with a natural formula.

Postpartum baby tips: Week 45 after birth

The 45-weeks old baby is learning and developing gradually this week into the life of a toddler from a newborn. Therefore, the parents can expect a lot of changes in their baby that come in naturally. Perhaps, here are a few tips to help you stay aware of certain changes during this week:

Your growing baby

Here are a few changes your growing baby will go through in the 45th week:

  • The toddler will now learn and grasp the concept of “NO,” from you. Perhaps, expect the baby to tease you at every chance she gets, and laugh it out in awe.
  • The 45 weekers might also learn to pass a mischievous grin as and when they do something wrong. This is more to get your attention than to be rebellious in nature.
  • They’ll like to play pretend on the phone just as you do, perhaps imitating to talk to you over the phone.
  • Your baby might have also learned to shake their heads and use single-syllable words.

Your baby being tantrum ready

Yes, the little sweet adorable kid is now capable of throwing tantrums, so be cautious. Here is what you can expect from your baby:

  • With their growing autonomy and still improving communication skills, don’t be shocked if your baby starts throwing mini temper tantrums when they wish to have something.
  • This is because your baby as an individual begins to grow their own personality, with some sensitive or high-babies needing that might result in a minor disruption.
  • However, do not adhere to your baby’s tantrums as this will only teach them that being loud can get them what they wish to. On the other hand, you must leave your baby alone in their crib or room and make sure they know that it isn’t something worth a reward.  

The need for games for your baby in order to build motor skills

  • Peekaboo/Hide and Seek

Play hide and seek with your baby in the house, but do not hide for too long. This helps your baby understand that even if they aren’t around you are always there, and also help get over their separation anxiety. A word of caution, make sure your house is baby-proofed.

  • Tunnel

You can erect a play tunnel for your baby for them to crawl through and come out from the other end. Make sure you are not getting the little one trapped in a long way tunnel as it leads them into fear.

  • Point Game

Ask your baby to point out things in a storybook and also name it. This will help the baby to learn new names and their visuals.
