Re: Supply at growth spurt
As long as your baby is continuing to produce a normal amount of diapers and is being nursed on demand, I see no reason to worry. At first, most moms overproduce milk, and all the extra milk means that they feel full pretty often, particularly if the baby suddenly skips a few feedings in a row (i.e. sleeps through the night). But our bodies are smart, and they generally don't overproduce for long because it's a waste of energy and puts a mom at increased risk for plugged ducts and mastitis. Our bodies also have smart internal clocks, which means that we can be trained to make more milk when it's required, and less when it's not.
Basically, it sounds like your supply is now just right for baby's needs, and your body knows to not go crazy producing a ton of milk at night, when your baby is sleeping for a long stretch. If you're still worried, watch diaper output- as long as that continues to be normal, you know baby is getting plenty of milk. And I f diaper output is normal and even then you're still concerned, don't be afraid to add in a nighttime dream feed.
