Thanks so much for your quick response! They were born at 35 weeks, but required no special care. Our ped says to adjust for about two weeks. They have met every developmental milestone thus far on time, however. I have not really experimented with extending A time in the morning because up until the last few days, that was their best nap in terms of going down and staying down. If it ain't broke...But I am now questioning it because the rest of the day goes so terribly. We do put them in dark rooms, although its not totallydark, and gets lighter as the day goes on. We've tried white noise but it has actually caused more problems than its solved. They used to be swaddled but like to suck their thumbs, fingers, arms, etc. Swaddling them with their arms out seems rather pointless.
Thanks again,
Jessica
