As your little baby reaches around five months of age or 19 weeks, he is at the threshold of becoming a little person who is much more aware of his surroundings. He is not spending most of their time eating, sleeping, or pooping; rather, he is observing and learning with each passing day. His communication is better, and he can now make mesmerising cooing sounds and cutely chuckle when you try to make him laugh. There are so many amazing 19-week-old baby development milestones that you would love to know. Let us acquaint you with what you may expect from your 19-week-old baby in the following article.

A 19-Week-Old Baby’s Development

You may notice your little one changing fast in the first few months after birth; this is because babies tend to grow and develop really fast in the first few months. You may notice rapid growth and development in both mental and physical spheres. However, all babies grow at different paces and speeds, and if you notice your baby achieving certain milestones faster or slower than other babies, there is no need to worry.

Around week 19, your baby may weigh or your 19 weeks old baby weight may be around 14 to 15 pounds approximately and may measure around 24 to 25 inches in height.

Here are some common milestones that your baby may achieve by the time he is 19 weeks old:

Your baby may start recognising people and may even smile at known faces or the people he sees on a regular basis.
Your baby acts fussy and irritable around strangers and may cry too. This indicates that he may become choosy and may want to be around only those people he feels comfortable with.
Around this time, you may expect your baby to make cooing sounds, like “aah” or “ooo.” (2)
Your baby will enjoy it if you sing, tell him a story or simply hum any tune to him. He may not understand it, but he may enjoy all these activities. You may play games like peek-a-boo with your baby, too. Your baby loves to engage in activities and games around this age. He may also smile or chuckle if you make him laugh (3).
Your baby’s leg muscles are becoming stronger, and you may notice his efforts to stand when you hold his hands. It will be a good idea to massage and engage him in some light exercises at this stage for strengthening his legs (4).
Your baby may have shorter naps around this time, and he may want to spend more time being up and active.
Your baby’s eyesight is steadily improving, and they will start relating their vision with other senses, including hearing, taste, and feel (5).

Feeding

Most babies at this age are exclusively on breast milk only, but sometimes you may find your baby fussy and cranky during the feeding sessions. Though in some cases it may be due to a lack of milk from the breast, in most cases it is due to the developmental changes that your baby may be going through. This is because your baby is more aware of his surroundings and may easily feel distracted and thus become fussy and irritable. You may notice this pattern is more prominent during the day feeding sessions in comparison to the night feeding sessions. Your baby may show the urge to feed but may latch on only for a short duration, and they may become frustrated and cranky. Your baby’s erratic behaviour does not mean that your milk supply has gone down, and you should not start with formula or solid foods. Your baby may be feeling overwhelmed with the growth and development process and may take a little while to make peace with it.

The best thing that you can do as a mother is to soothe and calm your kid and make sure there are no distractions around whenever you plan to feed him. Create a comforting environment and try feeding him. Though this stage may be pretty daunting for the mother too the good news is that it is just a temporary phase and shall soon get over. Be patient and offer to feed as and when your baby wishes to feed. Your baby may prefer night feeds to the day feeds; thus, this pattern may make your breasts feel too full. Try hand or pump for expressing extra milk to release the pressure.

Sleeping

The erratic feeding schedule may affect your baby’s sleeping pattern, too. A 4-month-old baby is expected to sleep about 9 to 10 hours at night with two moderate naps during the day, making up a total of 14 to 16 hours of sleep per day (6).

The brain developmental phase may start affecting your baby’s sleep schedule, and this may prevail for a couple of more months. You may comfort your baby by snuggling with him and sharing the same bed. This may ease your baby’s restless attitude and the feeling of unsettledness. As your baby may want more feeds during nighttime, sleeping with your baby will give him easy access to them. Look for sleeping cues like yawning, rubbing eyes, fussing, and looking away (7). If you notice any of these signs, help them settle down, as further delay can cause them to cry or get overstimulated.

You may even notice your bottle-fed baby getting up more during nighttime, too. This may not be because of hunger but because of the general feeling of unsettledness that babies experience around this age. However, you may not be required to offer a bottle to your baby, but you have to work on techniques to soothe your baby. You may offer your breast or a pacifier to soothe your baby to go back to sleep.

However, you should limit the use of the pacifier and only use it when it is required the most. You may also make yourself and your baby feel comfortable for the night feeding sessions by placing some extra pillows for support. The above-mentioned tips may help your 19-week-old baby sleep better.

Hearing

At this stage, your baby can cherry-pick different things from your speech, like the sounds you make or the way you make sentences and how your mouth moves while making those sentences. Your baby may also learn to respond to their names, although not very clearly.

Fussy at 19 Weeks

A 19-week-old baby often goes through several developmental changes that can lead to increased fussiness. This period can involve neurological growth, physical limitations (wanting movement and engagement but not yet able to fully control it), and social awareness, all of which may make your baby clingy, cranky, and harder to soothe at times. This stage is temporary and generally part of normal infant development.

A 19-Week-Old Baby’s Care Tips

Here are some care tips that you may use to care for your 19-week-old baby:

When to Consult a Doctor
