C.K.
I would give up one of the naps, and perhaps try an earlier bedtime if you feel she needs it.
My son is also 1. months old. He sleeps from 7:00 p.m. to 6:30-7:30 a.m. He gets one nap, usually from 1.:00 a.m. to 1:00 p.m., although some days he sleeps for only 45 minutes or so. He abandoned his second nap a few months ago!
