siria i have found that L can do less A time in the afternoon. some other people are the opposite. maybe don't do an even split? esp with a short nap. I do go by the clock now, not A times. just a suggestion...
here is our routine (been like it a while now)
6.30 wake
12 nap - sometimes 1.15, sometimes 2hrs.
bed, asleep by 7.
if a few days of short naps, i will do 6.30 bedtime.
hth!
