As new parents, it might be difficult to get a decent night's rest when your precious 3 week old baby keeps crying. However, that's the only way your baby can communicate with you right now. You might feel exhausted and frustrated for now, but remember that your newborn won't stay small forever. Let's see what 3 week old baby development milestones are in store for your little one.

3 Week Old Baby Development

Physical Development

By the third week, your baby's skin should be peeling less and looking more plump, pink and clear. Don't worry if your baby still has cradle cap – that rough scaly dandruff-like skin on his scalp – because most of the time, it will go away on its own. It might look unsightly and uncomfortable, but it won't bother your newborn.

As part of 3 week old baby development, his movements might be jerky and uncontrolled, which is normal for a newborn. This is because your baby's nervous system and muscle control still need time to mature. In time, when his muscles get stronger, his movements will become more and more fluid.

It is likely your baby will still be sleeping most of the time, just make sure to put him down on his back as that is the safest sleeping position. But during the short moments that he is awake, you can put him on his stomach to do some tummy time. This helps strengthen the neck muscles so they can push up to sit, roll over and crawl in the later months.

Cognitive Development

At three weeks, your baby is still trying to adjust to being outside of your womb. Loud noises will still startle him, trigger the waterworks and his Moro reflex. To help him calm down and feel more secure, you can always try swaddling him. 

But did you know that you can also comfort your newborn by talking softly to him? Your little one can recognise songs or sounds he heard when he was still in your womb and mum's voice is one of the sounds he hears the most.

Another way for a baby to soothe themselves is by sucking.  However, if you are nursing, you might want to wait until breastfeeding is well established before offering a pacifier so they can self-soothe. Even if you don't offer a pacifier, sucking on his own fingers will also help your baby to self-soothe.

Now it might seem as though all your baby does is feed, poop, sleep and repeat. But his brain is actually absorbing a lot of new things during his 3 week old baby development phase. 

A good way to help him learn is to put your face in front of him during tummy time. Allow him to study your face and copy your lip movements. It might be very subtle, but if you watch him carefully enough you might actually notice him trying to copy you.

Nutrition and Health

Breastfeeding should be well established by now, and your breasts might be full and heavy with milk. There is no hard and fast rule about when to nurse your baby. At this age, feeding on demand is still best. The best way is to take cues from them and feed whenever they need it, as babies typically know exactly how much food they need.

As long as your baby is latching well, satisfied and gaining weight, then all is well. Check for lip and tongue ties if you have facing breastfeeding problems. You will still be able to breastfeed if your baby has a cleft lip or palate.

Also, remember to let baby drain each breast at each feed so you don't suffer from blocked ducts or mastitis. 

If your baby was already having colic problems before this, then it might probably still be there during his 3 week old development phase. While it might be heartbreaking to see your little one so uncomfortable, this too will also pass. However, if it seems to be getting worse, his paediatrician might be able to offer some relief. 

There are a few red flags that you can look out for, and make sure that your baby gets immediate medical attention:

  1. Respiratory Distress: If you see rapid breathing, flaring of the nose, grunting while breathing or bluish skin that refuses to fade, your newborn might be having breathing difficulties.

  2. Constant vomiting: It is normal for infants to spit up milk after feeds. But frequent vomiting is not. Be sure to mention this to the paediatrician. Your baby might be lactose intolerant or allergic to breast milk.

  3. Oral Thrush: When yeast starts manifesting in your baby’s mouth, it might end in oral thrush. Talk to your paediatrician and see if your little one needs a prescription of anti-fungal medication

Newborn Care

Make sure you do not shake your baby especially when they won't stop crying. Your baby's neck is still very weak and cannot fully support his head. Shaking can cause your baby’s fragile brain to slide back and forth within his skull, possibly inflicting irreversible brain trauma also known as shaken baby syndrome.

Ensure that the room your newborn is sleeping in is of the right temperature. The ideal room temperature is 24ºC if you are using an air conditioner. At this temperature, their body is not fighting to stay cool or trying to warm up.

Here's another tip for mums with baby boys: remember that when cool air hits your newborn's private parts, it might make him pee. So open his diaper slowly and with caution, so that you can catch the stream before it goes everywhere else!

New Parent Wellness

If you can get extra help around the house, take it because chances are you will be tired and sleep-deprived. Nap when your baby naps. You can always live with a bit of mess at home as long as you get sufficient rest.

Even if it is difficult going through your 3 week old baby development and milestones, remember that they don't always stay that small and dependent on you forever. Like many parents before you, you will pull through as well.

Enjoy this epic journey of getting to know your little one and create new memories one day at a time. Someday you will look back and remember that it was well worth it.
