Just like newborns, fetuses spend most of their time sleeping. Indeed, throughout much of the pregnancy, your baby sleeps 90 to 95% of the day. Some of these hours are spent in deep sleep, some in REM sleep, and some in an indeterminate state—a result of their immature brain.
At 11 weeks, the brain cells that cause us to fall asleep are not yet formed, but this will happen soon. Before it does, your little one will be in a constant state of sleep. By this time, the brain cells that cause your baby to fall asleep have formed, and they'll start waking up and falling asleep in cycles.
For most of the pregnancy, your baby sleeps about 95 percent of the time, even as you feel it moving or hiccupping.
If the baby in utero feels any sort of distress due to any reason like reduced blood flow or placental insufficiency, the movements are reduced. They first become lazy and sluggish and sometimes, the heartbeat also goes if you neglect the early signs of decreased movement.
Researchers in Scotland compared fetal responses when pregnant women spoke to their babies or rubbed their bellies. "Overall results suggest that maternal touch of the abdomen was a powerful stimulus, producing a range of fetal behavioural responses," the researchers write.
Babies in the womb respond to external stimuli, especially when it comes from the mother. They simply love this interaction which is why you and your spouse might often find your baby in a playful mood when you play the touch-and-feel game together.
And the bonus? Baby may start to know when their father is touching mom's belly. Babies can sense touch from anyone, but they can also sense when touch (and voice) is familiar. And by 24 weeks into pregnancy, dad can usually feel baby kick – but the exact time varies.
Most people find the first six to eight weeks to be the hardest with a new baby. And, although people may not openly discuss many of the challenges in these early weeks of parenthood (if at all), there are a number of common hurdles you may face at this time.

Babies are most active after meals or if you've just had some caffeine or sugar. You can help nudge baby into wiggling with a glass of cold milk (or anything else chilly and sweet) and lying on your side to increase blood flow to baby.
The baby is well-protected in the uterus, and even a hard sneeze will not affect the baby.
But when a mother laughs, says Als, ultrasound images show that “the baby kind of trampoline bounces.” When she laughs harder, the baby bounces even more exuberantly. “It's fascinating,” she says. “There's such an interaction between mother and child on all levels.”
Do babies sleep during labor? During labor, just as in pregnancy, your baby still experiences periods of sleep. A typical sleep cycle will generally last somewhere between 20 and 40 minutes, but usually no longer than 90 minutes. These patterns will be evident during your labor.
Sleeping for more than nine hours per night, without disturbance, during pregnancy may be associated with late stillbirth, according to US researchers. Their study suggested that maternal sleep habits, including lengthy periods of sleep without waking more than once in the night, may be associated with foetal health.
At 15 weeks of pregnancy, you are in your second trimester and will start to notice big changes. However, according to some researchers, it isn't until about 21 weeks of pregnancy that your baby may begin to feel sensations when you rub your belly.
Research has shown that, during pregnancy, your baby feels what you feel—and with the same intensity. That means if you're crying, your baby feels the same emotion, as if it's their own.
On average, between fertilization and birth, your baby's heart will beat approximately 54 million times! Your baby can hear both inside and outside of the womb at 16 weeks! Most of the ear structures required to pick up sound are formed at this time.
The fetus is most vulnerable during the first 12 weeks. During this period of time, all of the major organs and body systems are forming and can be damaged if the fetus is exposed to drugs, infectious agents, radiation, certain medications, tobacco and toxic substances.
In the United States, most births occur between June and early November. Count back nine months, and you'll see that places most conceptions in the fall and winter.
First Trimester (0 to 13 Weeks)
The first trimester is the most crucial to your baby's development. During this period, your baby's body structure and organ systems develop. Most miscarriages and birth defects occur during this period. Your body also undergoes major changes during the first trimester.
For some moms-to-be, constantly touching, patting, rubbing and holding their belly can be soothing. For others, it's a way to feel close to the baby inside. But no matter the reason, rubbing your belly simply makes you feel good.
The more your partner touches your tummy during pregnancy, the more familiar that touch becomes. This increases the bond for the whole family. This is especially true when touch is combined with sound. Your little one can hear the sound by 16 weeks.
Around the 23rd week of pregnancy, the fetus will also be able to hear noises from outside of the womb. These include speech and music. As the fetus develops, all of the sounds will become louder and more distinguishable.
