Why do babies startle in their sleep? Some babies startle for no apparent reason, but usually it's in response to a loud sound, a sudden movement, intense light or the sensation of falling —like when you put your little one down in their crib. Babies can also trigger the moro reflex themselves, when they move suddenly.

• Feel their head low down in your belly
• Feel their bottom or legs above your belly button
• Feel larger movements — bottom or legs — higher up toward your rib cage
• Feel smaller movements — hands or elbows — low down in your pelvis

Your unborn baby's first muscle movements were involuntary, but the first voluntary muscle movements occur around week 16. After this point, awake or asleep, they move 50 times or more each hour, flexing and extending their body, moving their head, face, and limbs, and exploring their warm, wet home by touch.

Yes, it's perfectly normal for your baby to appear angry sometimes. It can be very upsetting to see your baby distressed, but this is something most babies go through from time to time. Your baby probably isn't feeling anger in the way adults do.

Like many saccharine terms of endearment ('honey' and 'sweetie' among them), 'baby' is gentle and kind—an expression of our best self loving another. It signifies a desire to care for and protect our partner unconditionally.

When your baby is between 1 and 3 months old, she'll be gradually gaining the strength needed to hold her head up. By around 2 months, while she's lying on her stomach, you might notice she can raise her head for just a few seconds at a time. These brief moments help strengthen the muscles in the back of her neck.

In most cases, “watch and wait” (with lots of extra tlc) is the most appropriate course of action after a baby's minor head bump. Keep the symptoms of a more serious head injury in mind, watching for any changes in behavior or neurological deficits within 48 hours of the accident.

A single sperm and the mother's egg cell meet in the fallopian tube. When the single sperm enters the egg, conception occurs. The combined sperm and egg is called a zygote. The zygote contains all of the genetic information (dna) needed to become a baby.

According to the affection exchange theory, which was proposed by the communication researcher kory floyd, specific vocal behaviors signal affection. These include the use of a high pitch, exaggerated intonation and a soft voice—traits that just so happen to overlap with the way most people talk to babies.

Sometimes they take longer and slower breaths and then shallower intakes of air. Occasionally, noisy breathing is caused by the sound of air flowing over the saliva in the back of the baby's throat. As adults, we can clear our throat as we need to but babies don't have this ability.

Well, oddly, the word does do something to the female brain. It releases a certain chemical in our brain -- oxytocin. According to numerous catalogs discussing stress reducing techniques, being called 'baby' has a positive effect on the female brain. It causes instant emotional stress relief.

They'll start sitting with support (leaning on you, or propped up on pillows) once they have good head and neck control, usually around 4 to 5 months old. Soon after, babies learn to lean forward on their hands to balance while sitting. Between 6 and 8 months old, babies get the hang of sitting independently.

Calling you baby is not offensive, and, as mentioned earlier, it's a great way to gauge if you're interested. One of the reasons so many men love it is that they can slip it into casual talking. It doesn't put you on the defensive. Girls love it as a nickname because it makes them feel delicate, soft, and adored.

Your guy loves you and is saying it by using this pet name. The exact reason may be fuzzy and lost in time. But if you're in a relationship and your guy is calling you baby, it means only one thing. He wants to show his love for you, so he's using an intimate term.

It means she's into you. When a girl starts calling you 'baby' while chatting, it can mean one of two things: she either really likes you and is trying to show her affection, or she's just being friendly and doesn't really have any romantic feelings for you.
