S.H.
If baby needs to nurse, just nurse.
There is also what is called 'cluster feeding" and this means a baby will even need to nurse every single hour. Normal.
It also serves, to make your body, produce enough milk per their needs/growth/development and per growth-spurts.
Not all babies take pacifiers.
6 weeks is a growth-spurt period in a baby. Every 3 week is one.
Then at 3 months, 6 months, 9 months and every 3 months.
Appetites, fluctuate and per time of day. Just like Adults.
Hunger is not static nor predictable.
Pumping and bottle feeding: IF you are going to give a bottle, INSTEAD of direct nursing, this will decrease, your milk supply. So know that.
BUT, if you use a bottle as a chaser AFTER nursing, then that is fine.
Anytime you decrease direct nursing, your body will then produce less milk.
I would not give a bottle to a 5-week old, unless you have to. Since you are breastfeeding.
Also, some babies, will then ONLY take a bottle and may reject breastfeeding. Because, bottle sucking is easier, than sucking from a breast. Bottles just require gravity. But breastfeeding requires a mouth/tongue coordination and working to get the let down out.
And some babies, get nipple confusion.
Know a baby's hunger cues. ie: rooting, turning toward you, fist to mouth, crying, etc.
Again, an infant does not feed according to a schedule. It varies and per growth-spurts too. Thus, the need to nurse on-demand. This then keeps up WITH the baby's needs for intake.
And yes, at certain junctures, a baby will nurse constantly.
Breastmilk, metabolizes quickly.
And when cluster-feeding, they feed all the time.
Just nurse, on-demand.
