Hi there, I'm sorry, I know you've had a few other threads going on at various times and I've just tried to look back at some of them to try and get an idea of the bigger picture. One thing I'd find really interesting would be how he seems during his A times? I mean, does he seem generally bright and happy, or are there times when he's really struggling to hold it together, or alternatively does he ever seem kind of crazy hyper/delirious? Not always easy to tell, I appreciate, but both of mine have certainly been capable of going completely crazy in an often hilarious way, but obviously caused by OT. Or on the other hand have more tantrums etc than usual, or just want to lie down, etc. I can generally be confident that mine are getting enough sleep overall if they're on an even keel, so to speak - yes, DS really needs to have lots of physical exercise or else he's bouncing off the walls (as a baby, I found he needed to get outside regularly, even before he could walk around himself) - but on days when I know they've each had what they generally need, and are well etc, I can often put 'crazy' behaviour down to OT and then I know I need to try and get a little more sleep into them. Sorry I'm rambling, but my point is that you know your DS best, and so I feel I need to know how you feel about whether he's getting enough sleep overall - I could guess that he's OT (as my LOs probably would have been with those sorts of naps) but if he's really doing fine during the day and on an 'even keel' then there's probably little point in trying to get more sleep into him and we'll need to aim for something with a little less daytime sleep, perhaps, or just longer A times. Does that make sense at all? So, how do you feel he's really doing?
Btw I noticed you've kept switching between wanting to do long am, short pm naps, and vice versa. So just letting you know we did short am, long pm with both of ours - for DS it was clearly his natural rhythm; with DD I think she'd have got on better with the other way around but we kind of had to force her into the same thing in order to fit around DS, and it did kind of work out OK in the end
We found a really consistent routine before the am nap and a consistent beginning and end time really helped with this. But anyway, more on that if you decide that's the way you want to go - I'll hang back for others to advise if you want to keep with the long am nap
