Spittlebug?

Having a hard time trying to figure out how much formula Aidan should get, now that I've stopped breastfeeding. He'll eat a 32 ounce bottle if we let him, so we have to gauge it now by how much he spits up afterward. Six ounces=massive spit-up. Five ounces=minimal spittle. Doctors "say" he's a baby. But could he really be a spittlebug? The world may never know.

spit·tle (sptl) Pronunciation Key n.
Spit; saliva.
The frothy liquid secreted by spittlebugs.
