You have taken such good care of your little one and we know you will continue to do so. In the last three months, you must have learned enough about raising children and trust us that your little one appreciates your efforts. At 15 weeks, your baby may try to interact with family members, showing its cute grin. The 4-month borderline phase is full of developments shaping your baby.

Baby Development

At around 4 months old, your baby may surprise you (and itself!) by rolling over. Babies often switch from front to back first, but it`s perfectly normal to do it the other way around. Give your baby plenty of tummy time to strengthen the muscles it will need for rolling, sitting, crawling and other motor skills. You can also encourage your baby through play: If it’s interested enough to try turning again, play a toy next to the side it’s rolling on. Applaud your baby`s efforts and smile. Since this new skill can be intimidating, your little one may need your confidence.

Your bundle of happiness will appreciate your efforts like making funny faces. It may show its gratitude to you with a smile or a giggle. It may also understand that peekaboo and hide-and-seek games won`t really get you off and you`re just trying to entertain it. When you cover its toy with a blanket, it will understand that removing the blanket will reveal the toy. If you have a cute nickname for your baby, it may even start responding to it. By hearing the different tones of your voice, it can get an idea of your emotional state. When you say a firm `no`, it may not understand what it means, but it will understand that you are not happy and should stop doing what it is about to do. Now it can see all colors clearly, so the world is more beautiful for it than before!

Milestones

1. At 15 weeks, your baby can easily and forcefully turn its head to look at something interesting, follow your movements or respond to a sound.

1. Now your baby can respond to your presence, voice and even facial expressions by waving its arms and kicking its feet.

1. When your baby is safely in your arms, it will be interested in interacting with other people - especially noisy children.

1. By this time, your baby`s vision will also develop and its other senses will begin to combine to form a harmonious sensory network.

1. Your baby can understand different colors. It will gradually begin to understand the differences in shapes. This is a sign of brain development.

1. It begins to understand that its limbs have different uses in various scenarios. For example, it may try to slide the toy with its hands.

1. Looking in the mirror may be one of its favorite activities during this period. It observes itself and can understand how its limb actually moves when it moves it. Body-eye coordination will accelerate.

Nutrition

As its brain develops and its ability to communicate strengthens, your baby fed properly at certain times may suddenly want to play and eat at the same time. Curiosity will prevail and it will always want to learn a lot of information and discover everything its eyes see. This can cause a small feeding session to go on for a long time as your baby feeds a little, then gets distracted by something and then feeds again. Let it satisfy its curiosity, it may refuse to feed if you try to force-feed it. Alternatively, you can draw its attention to feeding, by wearing a necklace around your neck, making animal noises, singing a funny song, looking into its eyes, touching its cheeks and triggering the sucking reflex, etc. If it is very distracted, make sure that there is nothing striking in its vision and that the environment is quiet.

If you are planning to start working again or working from home, you will undoubtedly need to make some changes to your routine. Before you need to go to work, you should regularly express and store your milk.

Sleep

The phrase "sleeping like a baby" may make more sense to you these days, as your 3-month-old baby begins to sleep longer at night. It should sleep about 15 hours a day. Avoid activities that are over-stimulated and exciting that will cause your baby to refuse to sleep before bed. Incorporate humming a slow, soothing tune into your routine that it’ll associate with falling asleep.

Care Tips

1. Starting this week, you will need to be extra careful with it as it will start to move and roll well.

1. Your baby now revolves around it, never leave it unattended. Even if it isn`t returning yet, don`t let it go, because the first time it learns to return may be the moment you leave it alone! If you`re going to leave it alone for a few minutes, be sure to let it enjoy itself on a railing bed.

1. Do not let your baby sleep on its tummy unattended until it has its head elevated.

1. Your little one may start to drool even more this time around. Excessive salivation can be a sign of teething. So keep checking for teething marks. Some babies can have their first teeth in these months.

1. In large groups or with unfamiliar people, your baby may need time to get comfortable. Allow transition time when leaving it with strangers or a caregiver.

1. If you are going to return to work, make sure to observe how the caregiver interacts with your baby beforehand. It can be helpful to start developing a quick and simple "goodbye routine" to help both you and your baby get used to the breakup.

1. Many chubby babies become weaker once they start crawling and walking. As your baby grows, you can keep it fit and healthy by encouraging floor play. Feed it only when it`s hungry and avoid using a bottle to calm it down when it’s upset or stressed. Instead, offer it a toy or love and kisses.

Tests and Vaccines

If the previous vaccinations, tests and controls have been applied correctly and on time, there will be no need for another health routine during this week.

Plays and Activities

Sounds accompanied by other sounds will begin to be recorded in your baby`s brain. You can imitate the sounds of a dog and cat and create bird shapes using your hands. This will help later when you take it for a walk in the park. Your little one will recognize them instantly.

Let it hold the toy by saying take it, and then stretch your hand towards it and ask it back by saying give it the toy. So you can lay the foundations of the give and take game. Of course, these toys should be light enough for it to hold.

When to Apply to The Doctor?

If your 15-week-old baby is crying a lot and nothing you try is calming it, there may be something bothering it. You should take it to the doctor. Most babies try to turn around by this age - this is an important physical milestone. If your baby doesn`t show a single sign of doing so, you can consult your doctor to make sure your baby is developing normally.

Around this time, some babies begin to show signs of teething. To help your baby, you should learn about the early signs and symptoms of teething in babies. If your baby is drooling a lot, is irritable and cranky, and tries to bite off anything in sight, it may be starting to teethe. You can get teething toys to relieve teething pain.
