Build a two-nap day from a wake time and wake window length.
The first nap starts after the wake window from waking, then each subsequent nap is placed after the next wake window, wrapping past midnight when needed. Following wake windows rather than the clock keeps naps aligned with the baby's biological rhythm and their sleep pressure.
Nap Schedule
Nap start = end of prior sleep + wake window (24-hour wrap)
