How soon should a baby learn to sit up unassisted?

Question

I need to know when it is that a baby should learn to sit up in an upright position without any form of assistance.

Answer 1

All infants reach developmental milestones at different times. The textbook stage for sitting unaided is 6-9 months. Most babies can pull themselves to a sitting position and prop themselves before this.

Answer 2

On avg, it's between 6 and 9mths that most babies can sit up unassisted. Some can earlier, some perhaps later, but it rarely indicates a developmental disorder for babies who wait as long as 9 mths to start. And 6mths is still much too early to expect babies to pull up to a standing position... next we'll have 18mth olds starting to drive cars!

There are all sorts of sites/books/etc that show what babies likely will be able to do at any given mth. Here's something from ivillage that says sitting with some support at 6mths is common while completely unsupported at the end of 8mths:

By the end of month six a baby typically:
Keeps head level when pulled to sitting position
Makes some vowel-consonant sounds
Sits by self with minimal support
Opens mouth for spoon
Reaches for and grabs objects
Rolls over and back
Drinks from a cup with help
Can hold bottle
Copies some facial expressions
Makes two-syllable sounds

By the end of month eight a baby typically:
Chews on objects
Reaches for utensils when being fed
Turns head away when finished eating
May sleep between 11 and 13 hours a night; takes 2 to 3 naps (may vary)
Rolls all the way around
Sits unsupported
Gets on arms and knees in crawling position
Has specific cries for various needs
Babbles enthusiastically
Tests gravity by dropping objects over edge of high chair
Responds to own name
Has different reactions for different family members
Shows some anxiety when removed from parent

Answer 4

Each baby is different and they do it at different times. You do not teach your baby anything. Your child knows when to sit, crawl and walk. It all depends on the make up of the brain. Some babies sit at 4 mos others longer. Some walk at 7 mos others 12 mos. Certainly dont push it. When your baby is ready he or she will just do it. Just make sure your baby has plenty of stimulation, play and interaction with others. If a baby lies in a crib all day or a playpen or a car seat they do not get enough stimulation to make the necessary connections in the brain for fast growth and development.
What to help your babies brain grow? Play music, read books, talk to him all the time, play silly little games, and cuddle your baby often. It will bond you like you have never bonded with anyone else. Love for Love, that is the secret.

Answer 5

Generally, it is 5-6 mos. before a baby can sit up unassisted. Keep pillows around the baby to fall over on while he learns to balance himself. But don't rush it! Before too long baby will be into everything and you will have no peace!

Answer 6

When Should Baby Sit Up

Answer 7

5 to 6 months

Answer 8

All three of mine sat unassisted around 5 mos old.

Answer 9

some as early as 4 months and some as late as 8 or nine months. My girl sat by herself around 6 months, but the age infants reach milestones like this doesn't predict their intelligence or how capable they will be later in life. So don't worry too much about it.

Answer 10

Depending on the baby it's usually 5-7 months or so.
