There is no "should" per an infant. If that were true, then ALL and every single 7 week old infant would be sleeping the same. But they don't.
Each baby is different. And their metabolism of intake.
I exclusively breastfed both my kids. They had GINORMOUS appetites, and I had tons of milk produced, and I would nurse them on both breasts each session and they would drink me dry.... and I nursed on-demand per their cues, and day and night they nursed anywhere from 1 hour to 3 hours all day and all night.
Also remember, that developmentally, an infant will also "cluster feed." This means, they feed even every single hour, and this is normal. Thus, you need to nurse, by their cues. It reflects their intake needs, which cannot be predicted by a clock.
You nurse, on demand, when baby needs to.
And yes, this includes during the night too.
Infants nap often. But, they all nap/sleep differently.
Some need absolutely NO noise, and some can sleep through noise.
Some need the same routine everyday, and some can sleep even if in a stroller or on the go. My kids... would not and could not, sleep/nap anywhere, except at home in their crib. I KNEW that. So I was home whenever it was nap time and bedtime.
I nursed each time, before a nap. And then after they woke.
Your infant, is normal. Normal, Normal.
Having an infant means no sleep for Mom.
Because, we have to nurse them.
And a baby needs to nurse, when they need to nurse. Not by a clock.
A baby, will typically get tired and need a nap, after about 2 hours of being awake. Even a bath at this age, is an activity for them and they get tired.
When an infant is over-tired or over-stimulated as well, it will make it hard for them to sleep.
So the bottom line is: know your baby's cues... for tiredness and hunger.
Your baby is only 7 weeks. They do not, have a set way of things yet.
All this time, they were in your womb. Now they are not. It takes adjusting. Adjusting for baby and Mom.
Just a tip: using a pacifier to get a baby to sleep... can also interfere with a baby's need for nursing. In other words, a baby may be HUNGRY and then be restless or wake because of it... but if you stick a pacifier in their mouth instead, they will STILL be hungry. A pacifier does not, replace... feedings or a need for a feeding. So you need to discern, that aspect as well.
The reason for swaddling is: a baby naturally has a "startle reflex." They have NO control over their limbs or motor movements. Thus when they move around, they wake. BUT, this is just their reflexes. No baby sleeps still as a statue. BUT so swaddling... makes a baby all wrapped up to lessen their movements/startle reflex... and thus, for some babies, they sleep better this way. But not all babies like to be swaddled. My daughter liked it, my son HATED it.
Each baby, is different.
So you need to know your infant's cues and needs.
BUT the bottom line is: even if you swaddle or give a pacifier... you STILL need to wake when baby wakes, and nurse baby. Day and night.
They need intake, and this is developmental and per their growth needs. They need a certain amount of intake, daily, night and day.
Your friends are wrong.
