To be honest, I'm not really sure if he is high or low on A times (that's sad!) because I've never really been able to tackle the nap situation. We had some great naps around 4.5 months and that didn't last very long! I would venture to say on the high side though, but he is spirited so I may just be mistaking his cues - the more tired he gets the more hyper he gets, he doesn't really 'slow down'. When we do wind down time it is very short because he quickly realizes how tired he is and then almost immediately starts crying.
I think maybe I will reduce a little tomorrow, maybe 2.35 just to see...can't hurt, clearly the 2.45 isn't working out for us!
The first nap he woke today he was just kind of neutral if that makes sense - he wasn't really happy, but wasn't upset either. When he woke from the second nap it started off the same (neutral), and I almost had him resettled after about 10mins of patting, until my dog barged in the room and woke him (I was still patting his back) and then he lunged into a screaming fit that was really hard to stop (which makes me think he was OT?).
