Baby's Ages and Stages

Sometimes, we are worry about the development of our babies and kidz, whether they are growth up without any delay in their development milestone.

Here is the age and stage of babies milestone:

Smiling ( age 6 - 8 weeks) :
a developmental milestone that most babies reach by the time that they are six to eight weeks old. There are actually two types of smiles for babies:

1. the spontaneous or almost reflexive smile that can occur early in the newborn period, and
2. the social smile that occurs in response to something, like when you talk or sing to your baby.

The social smile is a developmental milestone that most infants reach when they are one to two months old. Not having a social smile by six months of age is commonly considered to be an early sign of autism.

The spontaneous smile can occur as early as your baby's first few days of life and should be present by the time he is ten weeks old.

Laughing ( age 6 - 12 weeks):
a developmental milestone that many babies reach by the time that they are six to twelve weeks old.

It shouldn't be surprising that babies begin to laugh when they are six to twelve weeks old. After all, six weeks is usually when parents notice that colic which can make babies fussy, is starting to improve.

Rolling Over ( age 2 -6 months):
a developmental milestone that most babies reach by the time that they are two to six months old.

Rolling over is often one of the first major motor milestones that parents look forward to.

Spending less time prone or on their stomach, since the release of the Back to Sleep recommendations to reduce the risk of SIDS, has caused some infants to roll over a little later than they used to though.

It can also cause some delays in picking up other milestones, including sitting up and crawling. Fortunately, by the time they were toddlers, these delays all seem to disappear no matter how your baby sleeps, so it likely more appropriate to describe these kids as having a 'lag' in their development and not a true delay.

Still, most infants roll over when they are between two to six months old, first from their front to their back, and then from their back to their front.

Sitting Up ( age 5 - 7 months ):
a developmental milestone that most babies reach by the time that they are five and a half to seven months old.

Standing with Support ( age 6 - 9 months ):
a developmental milestone that most infants reach by the time that they are six and a half to nine months old.

First Step ( age 11 - 15 months ):
a developmental milestone most babies reach between eleven and fifteen months.

Waving Bye - Bye ( age 7 - 14 months ):
a developmental milestone that most babies can reach once they are seven to 14 months old.

Although waving hello and bye-bye seems like just a fun thing to teach your baby, it is actually an important developmental milestone. Most experts think that it can be an early sign of autism or another developmental disorder if your child isn't making any gestures by the time he is twelve months old. These gestures include waving, pointing, and reaching for things.

Keep in mind that most babies can wave once they are seven to 14 months old.

Pincer Grasp ( age 7 - 11 months ):
a developmental milestone that most babies reach when they are about seven to 11 months old.

Pretend Play ( age 10 - 16 months ):
Pretend play, or imitating activities, is an important developmental milestone that most infants reach when they are about ten to 16 months old.

Pretend play often involves things like using a computer mouse like a phone, imitating an activity a toddler has seen his parents do over and over.

Toddlers will also begin to copy more of their parents daily household tasks, such as dusting and sweeping, at around 18 months.

Pretend play will get more elaborate as your child gets older; for example, your child pretends he is a doctor, fireman, or race car driver.

First Word ( age 6 - 9 months ):
a baby's first words, which are usually mama or dada, and which you may hear for the first time when your baby is six to nine months old

Well before your baby's first words, your baby should be saying single syllables and frequently jabbering or babbling. Not babbling by twelve months is seen by most experts as an early sign of autism or other developmental disorder.

Most infants are babbling well before twelve months though. In fact, you will usually hear your baby's first words, which are usually mama or dada, by the time she is six to nine months old. Your baby won't use those words more specifically or correctly until she is seven to 13 months old though.

Parallel Play ( age around 2 years ):
playing next to each other, which is called parallel play, and is typical of most kids around age two.
