late arvo/early evening nap - what to do?

sleep promotes sleep, I would def let him sleep.

Why not make his bed time a bit earlier though? our DD goes to bed at 6.30 - 7 and sleeps 13-14hrs a night

C's bedtime has always been around 7pm so for us that meant letting him have that late arvo nap if needed but I always got him up by 5.30 so he'd be ready for bed again by 7pm.

Perhaps if you moved bedtime forward a bit you could keep him up longer or feel better about getting him up from the nap earlier IYGWIM?

I cant even remember, but shouldnt a 3 month old only be up for an hour or so at a time?

At 3mo DS was going for his late afternoon nap at 4:30pm and I'd wake him at 5:15pm for his bath and bedtime routine then put him to bed for the night at 7pm.  It's only been the last week that we've skipped the 4:30pm nap and even then there have been a couple of days when he's had 20 min snoozes to help get him through from 3pm - 7pm. 

As others have said sleep breeds sleep.

My nearly 8mth old is still having that afternoon sleep - she has a small nap in the morning, big slep (2+hrs) at lunch and then 45 minutes at 4ish. I would think that because he is still so young he would definteily need another sleep.

BecM, if what you're doing at the moment is working, then maybe it's just worth keeping at it for a bit longer. At that age Bethany would sleep late avo as well, then go to bed around 8/9. It just seemed to work for her. And unlike what everyone else is saying here, sleep never seemed to breed sleep for her - she always liked to do things differently!

We gradually brought her bedtime earlier, and one way we did it was by shortening the afternoon sleep. I felt it would be too cruel to put her to bed then get her up, so I'd put her in the sling and get things done around the house (or just sit on ohbaby lol) until I knew I needed to wake her so she'd still go to bed when we needed her to.

I will admit that we had sleeping issues with her from this point onwards, it seemed to start from her 3mth growth spurt, but regardless of what we did then, since 6mths old she's been going to bed at 6-7pm and now sleeps anywhere from 11.5-12.5hours overnight. So in the long run, I say take everything that's being said on board, but go with your gut cuz after all, you're his mum :) Let us know how you go! x
