Benign neonatal sleep myoclonus: sudden movements of their arms, legs, and face during sleep. It disappears on its own by 6 months. This is completely normal, and it just means that the infant's brain is active.
The baby displays involuntary and repetitive muscle jerks, termed myoclonus, in the trunk, the arms and legs, or the whole body. These movements happen when the baby is very young, usually between birth and 6 months old. Myoclonus occurs uniquely during sleep, and it always stops immediately once the infant wakes up.
This movement helps babies build muscles and coordination in the first several months. Infants may kick or stretch their legs to practice using their muscles and build flexibility at this stage of development. These reasons may explain why your infant slams their legs while sleeping.
Pulling legs up to tummy
Accompanied by fussing or crying, this baby body language is almost always a sign of pain — often normal gas pains. Colicky babies usually pull up their legs when they scream. What to doTry burping your baby, or hold her in a position that helps ease her pain.
Sleeping Curled Up Reminds Them of the Womb
When your little one is tuckered out with their knees pulled up under them, they're likely dreaming of one of their favorite places—the womb. If they're still young, they may have spent more time curled up inside than in the real world so far.
A number of ultrasound and animal studies have shown that the fetus has a circadian pattern that involves increased movement in the evening, and this is likely to reflect normal development.”
It's common to see young children body-rocking, head-rolling and head-banging at bedtime or during the night. They do it because it's rhythmic, and it comforts and soothes them. Children might: get on all fours and rock back and forth, hitting their foreheads on the headboard or edges of the cot.
Your baby's first laugh might arrive around one month after their first smile. Though 4 months of age is a common time for laughter to emerge, it could happen at 5, 6 or even 7 months old.
At birth your baby's eyes may appear gray or blue due to a lack of pigment. Once exposed to light, the eye color will most likely start to change to blue, green, hazel, or brown over a period of six months to one year.
The milestone of responding to one's own name usually occurs between 4 and 9 months, according to the American Speech and Hearing Association (ASHA). Not all babies reach this milestone at the same time, of course, but most should be appearing to recognize their name with consistency between the ages of 7 and 9 months.
Rapid Eye Movement (REM) or Active Sleep
The vast majority of newborns' smiles during sleep appear to occur when the eyes are moving rapidly, as they would during a dream. Studies suggest that adults smile in response to positive dream imagery.
You should stop swaddling your baby when he starts attempting to roll over. Many babies start working on this move at about 2 months old. Swaddling once your baby can roll over may increase the risk of SIDS (sudden infant death syndrome) and suffocation.
In the beginning, you may end up having to let baby cry it out for 45 minutes to an hour before she goes to sleep, though it varies from baby to baby.
When baby fights sleep, it can look all sorts of ways. Most commonly it's exactly what it sounds like- a fight. There might be screaming, crying, squirming out of your arms or fighting at the breast or bottle, and maybe even some tears out of you! Naps and bedtimes don't have to be this way.
Movement and Kicking in the Pubic Area
But don't worry, fetal movements in the pubic area are normal and very common, if not annoying. Call your doctor if you feel any kicking in your vagina, as a vaginal kick could indicate a rare but serious complication called cervical insufficiency.
Here's the funny thing about babies in the womb: They like to move when their moms are lying down. That's because when you're up and around all day, your baby-to-be is likely lulled to sleep by the movement. You're also less likely to notice her kicks and jabs when you're busy and preoccupied.
Sleep cycles consist of active sleep and quiet sleep. During active sleep, the newborn may move, groan, open their eyes, cry out or breathe noisily or irregularly. During quiet sleep, they will lie relatively still and their breathing will be more even.
It's OK to let your baby cry if the baby doesn't seem sick and you've tried everything to soothe your baby. You can try to leave your baby alone in a safe place, such as a crib, for about 10 to 15 minutes. Many babies need to cry before they can fall asleep. And they'll nod off faster if you leave them to cry.
Self-soothing
Many parents begin to pause before responding, or allow children to cry during bedtime without running to their sides around this age to teach children to sleep on their own. Even using this method, many suggest that babies should not be allowed to cry for more than 10 minutes without your attention.
Because of the likelihood of rolling onto the tummy, current advice for excessive crying in infants, suggests babies should not start wrapping after the fourth month, to un-swaddle as soon as the child signals they are trying to turn over, and always to stop swaddling before the sixth month, because after this age ...
Babies don't have to be swaddled. If your baby is happy without swaddling, don't bother. Always put your baby to sleep on his back. This is true no matter what, but is especially true if he is swaddled.
The AAP recommends that parents stop swaddling their baby (arms in) after they turn two months old. This is because swaddling becomes unsafe if: Baby starts getting strong enough to break out of the swaddle, causing there to be loose fabric in the crib.
When I'm pulling my lips into a little 'O' shape and widening my eyes, it's playtime. This look, wide open eyes and round little mouth, is a common one for excited babies who want to play with their parents. They might also clap, wave their hands, or even make a sound or two.
The answer behind this cute behavior might go beyond snuggles and snacks, though. A recent article in Frontiers in Psychology found that these types of sensory-seeking behaviors might be a comfort mechanism, a way to self-soothe when babies are feeling out of sorts, hungry, tired, or just overwhelmed.
