6-9 months--spoon feeding with thin purees, finger feeding of meltables, holds own bottle
9-12 months--cup drinking, finger feeding for melatbles and lumpy, mashed foods

88
Seeing aspiration during a FEES
Before: bolus falls into airway before swallow is initiated
During: bolus is not in airway before whiteout period but is immediately after
After: bolus falls into airway after whiteout period. residue is usually visible
89
Observing hyolarygeal elevation with FEES
Whiteout period=good hyolaryngeal elevation
