Sharing is caring!

When does a child sit up?

Babies have different timings in which they tend to sit properly and in general, they begin to make an attempt 3 to 5 months. They try to do so by propping up their heads or simply by taking the support of an elderly person around.

By the time babies are 2 months old, they can tilt their heads at an angle of 45 degrees by lying on their stomach. Then around 3 months, they move the head at a 45-degree angle while lying on the stomach and also move chest and hands. Then slowly they try to hold in that position steady till achieving an upright position.

Babies can sit with support when they are 4 months old while lying on the tummy. By the time they reach 5 months, they start raising the body on straight arms and hold steady with some kind of support.

Around 6 months, they can sit easily with support and roll over in either direction. By the 7th month, they can sit without any support and can shift the body easily by scooting or propelling on the stomach or back. By the 8th month, it becomes easy to sit without support and also starts to roll and crawl by lying on the stomach.

What makes babies sit?

Babies can learn sitting from day 1 but they can do it properly only when they have control over themselves. Especially it will take 100 days for them to have head control. By 4 months, babies head and neck develop rapidly and they will start holding the head while trying to lay back on their stomach.

Next, babies try to hold their head and chest from above the ground while lying on their stomach. During the 5th month, they will try for momentary sit up but they will need some kind of support from cushions or pillows.

Eventually, babies try out tripod position in which they will try to walk on their own. They will lean forward by forcing both their hands.

By 7th month, babies will feel like trying their hands out on different objects and lean onto anything they find helpful. It is the time when they will get to move with their tummy from the ground to maintain a good sitting position.

In short, their brain development and curiosity to hold things they find around to make them sit at the first instance.

How will you know that the baby is all set for sitting?

When babies have good head and neck control, you will feel confident of leaving them unattended for some time at least. Other body positions also slowly gain control. Slowly, they will show interest in rolling which indicates their want for sitting. They will roll over or simply move above the ground from lying on their stomachs. Support is needed at an early age so that babies don’t trip over. Hold babies for short durations to provide support.

Once baby crosses 9 months they will be rolling over in either direction. Some may scoot back and forth and also crawl at times. You can see that babies will try the seating position first before being able to try out sitting on their own.

Sitting requires a lot of physical strength and emotional confidence for kids. Thus regular practice will lead to gaining buoyancy in no time.

What is your role in making your baby sit?

With the help of signs, parents will know if their kids are ready to sit. Once baby attains proper neck and head control, then you can try out these simple positions to give them the time and attention that they require:

  • Sitting on lap starts around 3 to 5 months’ age of babies. Varying of hand movements is quite helpful either from the chest or simply towards hips. They can get trunk strength during this time.
  • When babies are around 4 to 5 months old, they will try to sit on the floor but between your legs. They can lean either left or right easily. They can even try to push their arms back to midline for better support.
  • When they are about 4 or 5 months old, they will try sitting on the bumbo chair. This chair is best for kids who are just starting to work on their upper trunk control. You can place some lightweight toys on the side of the bumbo chair or place it at a higher angle which will help to strengthen the back and chest of kids as they try to take them.
  • Kids also try to sit next to a laundry box or corner when they are about 4 or 5 months old. Laundry boxes can be used instead of bumbo chairs. It provides support from both sides. Babies can react safely with support and can move gently from side to side.
  • Kids can also sit using the Boppy pillow around 4 to 5 months of age. Surround your kids with lots of toys but at a safer distance so that they move to midline if needed.
  • Babies do the tripod sit when they are about 4 to 6 months old. In these positions, babies leap forward with their arms. Keep toys at a distance from which his eyes can see so that he can be encouraged to stand straight. The ring sit is for babies around 6 to 8 months of age. In these positions, the legs of babies are wide forming a circle. He may trip over to the front but take support with the help of one arm. He will be able to sit properly and use his hands for playing.

Your baby will sit on its own at the earliest after all your efforts and will try to reach onto toys which are located at a further distance. In this way, they will start moving from tummy position sitting while learning to trunk support.

What should you expect after baby sits independently?

After your baby sits up properly, the next thing would be lunging forward and using hands and feet for balance. They may try to hand forward when about 6 to 7 months old. Then they will crawl properly when about 10 months old. Now your child is all ready to be curious and take on an adventure in life. Consult a pediatrician before knowing if solid foods can be given at this stage.

Should you worry if your baby does not sit up?

It should be kept in mind that not all babies are the same and there is no such age for babies to sit up. Differences might be such that one might sit when around 5 months old while one may sit when 8 months old. It all depends on each individual baby, and their genes when to sit up and hence there is no such complication to it.

If to be seen, babies sit by and around they are 9 months old. They can also crawl properly during this age. They start crawling and moving along with unsupported events. If babies don’t walk when 9 months old, then it means your baby is a little late. They might get exhausted soon enough but they will muster the courage soon. Sometimes the case might also be because of development delays. Some signs may be as under:

  1. Head control is quite poor
  2. Muscles might be stiff
  3. Inability in reaching to toys that are far away

Changing these in babies might turn out to be a bit demanding for parents but they have to deal with it. Don’t bother too much but check with the doctor. They will know properly what is going on and give you better advice.

Sitting Vs Sitting up

When babies can sit properly, it means they have a properly developed spine that can handle their weight. Sitting up gives a new standpoint of life to babies. It helps babies to free their hands so that they can use it for other movements. Babies sit up mostly between 2 to 10 months of age.

Sitting is the first step whereas sitting up is able to sit in an erect position and make body movements like adults.
