Re: Not hungry for "breakfast"
Welcome to the forum!
In a 9 week-old baby, having some fast feedings in the mix is normal. Especially when the breast is very full, as it would be after baby sleeps through the night or takes a long nap. Because the breast is full, baby is getting a lot of milk in a hurry, and is probably bursting after just a few minutes of nursing. If you're concerned about intake, watch the baby's diaper output and weight gain. As long as those 2 things continue to be normal, there's no reason to worry. Just note that after 6 weeks, poop output sometimes slows to as little as one poop per week- though that single poop is likely to be a diaper-buster!
Allowing baby to sleep through the night is normally not a problem for production, as long as you are nursing on demand. Baby will make up for shortfalls in his nighttime intake by nursing more during the day, and if he needs more milk, he'll just start night-nursing again. (Don't get used to baby sleeping through- it is highly unlikely to last, especially once teething kicks in!) If you're concerned, you might want to consider taking away sleep-extending tools like swaddling and pacifiers, and sleeping in close proximity to your baby so that you can detect him stirring and nurse him if you desire to do so.
No need to pump- unless you're returning to work soon, in which case some pumping might be to your advantage. Is a return to the workplace part of your plan?
Also, how many times per day does baby nurse?
