Your newborn is normal.
A newborn is still getting used to our world.
They are still bonding as well.
They need to be held and comforted.
And yes, babies often just cry, for no "logical" reason that we adults can fathom.
Sometimes they are gassy too... infant gas drops helps this.
Babies ALSO cry or are not happy... because they are 'over-stimulated." A baby will cry, in order to shut-out extraneous stimuli. If you observe closely, you will get to know these cues in a baby.
My daughter was also sensitive to noises and being too hot. I knew that, as I got to know her as a newborn.
A newborn, is in a whole new world and sounds/tastes/temperatures/smells affect them. And, in this way, that is how they survive and "know" who their Mommy is. Its normal.
Your baby is very young.. this is normal. Babies cry. That is their only way to "communicate" and express their needs.
MANY MANY babies, sleep better on or with their Mommy. They need the comfort... they are no longer in a tight/cozy womb... and being held, close, to their Mommy feels right for them.
Yes, do NOT "expect" too much, too soon. EVERYTHING with a baby, has to be "age appropriate." They do things in their own time. When there are expectations that are too much too soon, it will only lead to frustration... mostly for the Parent.
Even their body and digestive system, their biological system is STILL developing, outside the womb. It is NOT easy for them either.
You want to be sure, you are feeding ON DEMAND, 24/7, day and night. They NEED the sustenance and calories, to sustain their rapid growth and developmental changes.
Make sure you are producing enough milk and that he is latching on properly... otherwise, he will NOT be getting enough intake. *Many babies cry, because they are simply hungry.
**Also, keep in mind, that MANY babies go through spurts of "cluster feeding." Meaning, they NEED to feed even every hour, all day. This reflects "their" intake needs, and it is their way of telling you they need to feed.
-make sure you feed on demand, NOT on a "schedule" or a baby will NOT be getting enough intake. Get to know what a baby's "feeding cues" are. The "rooting" gestures. You can look it up online.
MANY babies do NOT like car seats, slings, or swings. Bear in mind that at each age-juncture, these will vary. Both my kids as babies, HATED the car seat. It is common. Normal. YOu just deal with it. A baby will cry, and as you are driving, it can't always be avoided. They grow out of it. My son, HATED the car seat for his first 3 months. Normal.
I would NOT leave him in a swing, to sleep. He is a newborn and they do not have the neck/spine strength to just stay like that for a long time. A baby's "head" is VERY heavy, in comparison to it's body. Also, if using a swing to put him to sleep... it can become a "habit" that later, you may regret.
What you can try, is "swaddling" him.... look it up online, to see how, and perhaps buy sleepers that "swaddle" the baby. For my daughter, this is the only way she would sleep. For my son, he did fine in a Moses Basket. Each baby is different. But, I also co-slept with them. We have a floor futon in our room, and this is where I slept with my kids.
MANY MANY babies do not like cribs... it is an open expanse that they are not used to, after being in a womb.
You can also try "white noise" to put him to sleep. Some babies like this, as it replicates the noise that they heard in the womb.
And yes, this is what it is, with a baby.
A great book is: "What To Expect The First Year", which you can find at any bookstore or online like at Amazon.
In time, you will get to know HIS cues and needs. And then go according to that... instead of 'making' or expecting the baby to go according to what you think. I don't mean that in a mean way... but just as a good hearted way. ALSO, do NOT compare your baby to others... each baby is different... and they have their own time-line as to things.
BUT, make sure you are feeding on demand... that is very important. Most babies, as newborns....sleep a lot. ANd if they are "over-tired" they cannot sleep well. A newborn... even after being "awake" for even 2 hours, will get tired. Even a bath, at this age, is an 'activity."
All the best,
