So in the couple of weeks, DS' daytime caregivers (my mom and MIL on alternate days) have both been dipping into the freezer stash to supplement what I'm providing fresh. They say he's unsatisfied after getting a normal 4-5 oz bottle, and that he cries and appears to be looking for more.
Now, I'm sending 14-15 oz of fresh milk, and I'm able to feed him at 7am and 4:30pm, which is 9.5 hours, so I'm already sending a pretty good amount. On the days that they supplement, some of his feedings are up to 7 or 8 oz! From everything I read, this is way more than most BF babies take in a sitting.
DS is 6 months. It could be a growth spurt, so I want to be sensitive to his needs and make sure he's getting enough. On the other hand, if it's not a growth spurt, I need to cut off the extra supplements because there is no way I can keep up with pumping 18-20 oz per day!
My MIL has recommended putting rice cereal in his bottle (!) to keep him full longer. We did start cereal this weekend but DS was uninterested; it was fun to try, but I don't really think he's ready. If he continues to act hungry in the future perhaps solids might be able to fill in some of the gap?
In the meantime, what should I tell DS' caregivers? Should they continue to supplement when he seems unsatisfied after a feeding? If not, how should they deal with his apparent hunger?
