Hi all,
Michelle, don't know if this will help you but thought it worth mentioning that my LO, now 6 months, sometimes can't get to sleep for his catnap either. If he does get to sleep, it's either because he's missed out on naps earlier in the day (frequent occurence in our house), or he just falls asleep a lot later. Sometimes it's been as late as 5.30pm, in which case I usually wake him by 6pm. It does not seem to affect his night time sleep or how he goes down to sleep for bed. Bedtime is 7.30pm.
