6 mo. old male not taking daily naps for past 5 days. used to sleep every 2-3 hours for at least an hour at a time. any ideas/suggestions?

# of naps: Many babies are transitioning there napping behavior around this time. As newborns they just sleep and eat. By two months have a couple of hours a day they are awake. By 6 months, are really into exploring their universe, so not as much sleep. Still should have 1-2 hours of quiet time in morning and in afternoon, whether it be sleep or just cuddle and book reading time. That may encourage napping.
