The time change didn't seem to affect us too badly. Emma only woke up once, at 3:45am (new time), so their 7am wakeup wasn't too bad. Besides, we forgot to change the clocks last night, so it was 8am for us!
The co-sleeper is getting to be too small for both girls to sleep in, so we've decided to move Cora to the crib in the nursery soon. She started sleeping for 6 hours at night at one month old, and has been sleeping 8-10 hours for over a month now, so it makes sense to move her to the crib and keep Emma in the co-sleeper for a while longer. We're going to have to go crib shopping soon since we only have Abby's old crib right now. If any of you have a crib that eventually converts to a full-size crib, buy the rails to convert it right away! Abby's convertible crib turned out to be a waste because I couldn't find the rails anywhere when we were ready to convert it about 3 years after we originally bought it. Her crib style was discontinued, so no one has the rails anymore.
