We've been great with maintaining Ellie's CPT sessions to three times daily x 20 mins (approx times 9a, 4p, 12 - 2 am). She can easily sleep for 12+ hours and we're considering letting her sleep through the night without CPT and moving the three sessions to her actual awake hours (i.e., 9a, 3p, 9p). Because I still consider myself a "newbie", I would like to know if it's a poor decision to allow a 12-hour gap between CPT sessions. Will the extra few hours gained truly have ill effect as long as we're sticking to 3 sessions daily? Thanks.
