Yes, I think it's okay. A lot of times she only gets an hour afternoon nap. I just read that an hour and 15 minute afternoon nap is about average any way. (from the FAQ section);
1 year old:
Night: 11.5 hours;
Day: 2.25 hours - 2 naps, 1 of 1 hour and 1 of 1.25 hours;
Total: 13.75 hours
We are still dealing with early wake-ups. She seems to be consistently waking up at about 5:35 am. I may try the wake to sleep method, but the time I'd do Wake to Sleep was another Ritual Wake-up of hers (I think she's shed it though, because I haven't heard her wake at that time in a bit).
