6 Month Baby Development – What To Expect

Can you believe it? Your baby, who seems to have been born just the other day, is now 6 months old. They are halfway through their first year, and in another couple of months, you will be celebrating their first birthday. It seems just like yesterday that you were pregnant.

This is a big milestone month and a big age for a baby. Many things are happening in the 6th month. Not only has your baby turned into a real socialite, interacting with everyone around them and even welcoming the attention, but they are now probably rolling around everywhere.

One of the main milestones in a 6-month-old is the constant rolling. At this age, their strong neck and arm muscles allow them to do all of this. It will probably be very amusing for you and the rest of the household.

Now, as much as rolling all over is fun to watch, it can also be quite nerve-racking. Always be attentive, especially during diaper changes, and sleeping times. If your baby is on high ground, chances are that they will fall easily.

Keep them on the ground all the time and hold on to them during diaper changes. Let your baby sleep in a crib that is well reinforced for safety.

How Does Your Baby Look At 6 Months?

Looking at your 6-month-old baby, you can clearly tell that they have come a long way. Gone are the days when he would stay crunched up in a ball position all day long. Their head is also a nice round shape by now. In addition, their hands and legs have grown a whole lot.

Their weight should have increased by at least 1.5 – 2 pounds each month, and they should also be increasing in height gradually. At 6 months, your baby should weigh between 16.1- 17.5 pounds and their height should be between 25.9- 26.6 inches.

Please bear in mind, however, that all children are different and they develop on their own schedules.

Do not try to compare your baby with other babies. They are beyond compare, and in cases where your baby was born premature, their development may be slower compared to other babies.


At this age, they may have started to teeth. If they are crying unusually and have more drool than normal, then maybe their gums are swollen. Also, if they have a low fever, have trouble sleeping, refuse the bottle, and have some diarrhea here and there, they might be teething.


By now your baby’s senses are coming along just great. They may already be showing great improvements with sight, hearing, touch, and of course, taste as you will soon be introducing new foods.


Your baby should be able to focus at a distance and be mastering the idea of depth perception. They should be able to focus without getting cross-eyed and should already be familiar with their environment by now.

What should be evidenced clearly at 6 months is the ability to identify the familiar people (parents, close siblings, and other caretakers) and recognize strangers or guests who come to visit.

They should also be actively grabbing things and putting them in their mouth. They will be curious about everything. They should have the ability to pass things from one hand to another.

Their eye color should also have changed from the original birth color. The lighter colored eyes will go through several stages before settling into their final shade. And, at 6 months, if your baby still has blue eyes, chances are that they will remain that way permanently.

You will often find them concentrating while holding a toy, or staring intently at their own hands which are usually a big fascination for them.


Their hearing has also come a long way. Now they can clearly make out your voice and give a reaction to it such as a smile.

Sometimes, if you are a working parent, when you get home from work, you will find that if your baby was sleeping, the minute you speak after getting in the house, they will wake up. This is because even their subconscious minds recognize your voice.

At this age, they respond to the sounds he hears by making sounds themselves. They will not only utter simple “ah,” “oh,” “eh,” but also include some jabbering of consonants such as “m” and “b.” In short, they should be making attempts at speaking.

Congratulate yourself for getting to 6 months. You can even have a half birthday party for the little one because it is a big milestone. All in all, enjoy time with your baby because the infant time moves way too fast and soon you will have a fully-grown baby.
