I just don't know anymore. She used to get a lot less sleep when she was in a really bad stage with reflux and digestive issues. Her gut is so much better now so I think she is sleeping better than ever (for her anyway). With DS, I was always tweaking his A times and after a few tweaks, I could always get him back to a 2hr nap. But he is high sleep needs relative to her, at least it seems. She operates ok with little sleep which always amazed me when she was so little and up for hours at night but put on a smile the next day and was a happy little girl. I'm always paranoid about OT, so I always think it is OT, but she is showing me no signs of it except the short nap. Maybe that is just her sleep cycle? I just looked back in my diary and about 2 weeks ago, we were on similar A times (about 3hr15) in the AM and she was giving me 1.5hr sleeps. So maybe time for increase A? Which again seems high to me for her age, so maybe she is OT and just handles it better than DS did. Arrghh.. this is so hard!!
Maybe I will try a few days of shorter A's just to rule it out before pushing it the other way...
