S.H.
Cluster feed. Cluster feeding is NORMAL and means feeding even every single hour.
Especially when hitting growth-spurts.
Always feed on-demand... ALWAYS. So your body also makes enough milk.
Make sure he is latching on properly... otherwise a baby will not get enough intake.
Bottles.... are a different 'technique' for drinking... only by gravity. To nurse at breast... it requires the baby to have the proper tongue/mouth coordination AND to suckle to get the let-down going. Some babies... do not latch on properly to do that... maybe see a Lactation Consultant to make sure.
Drink water and stay hydrated. So you produce milk.
In an infant, every 3 weeks is a growth-spurt period. Then at 3 months and every 3 months. So then 6, 9, 12, 15, 18 months and so forth. Intake/hunger at these periods, increases and in terms of feeding frequency.
Get the book "What To Expect The First Year."
You CANNOT over-feed... an infant.
He seems to be hitting a Growth-spurt. At these times you have to feed ON-demand, 24/7, day AND night. VERY important.
Your son seems to have a GOOD appetite. BOTH my kids were that way... I nursed with both my breasts, per session... and they drank me dry and grew like weeds and my milk production kept pace with THEIR intake needs... and feeding frequency.
IF you give him bottles.... instead of breast... your breasts will produce less milk. Because it is not being stimulated by your baby. So do not do that or try not to.
He is ONLY 7 weeks old... and your body needs to adjust to HIS intake needs and appetite. Feed on-demand. Direct nursing.
You NEED to do direct nursing.... not bottles. Or your milk supply will not mirror your son's needs nor your milk production.
Do not replace, nursing with bottles.
all the best,
