K.U.
I worked hard to get my twins on the same sleep schedule and it really paid off. When mine were about 6 weeks, I read the book, Baby Wise and started using the sleep schedule they suggested and I swear it made them different babies- happier, well rested, etc. Mine are 21 months now and are still awesome sleepers. Congratulations and good luck, you'll find a routine that works for you!
P.S. If you haven't already, joining a Mothers of Twins club was so helpful for me just to have the support of other moms who get what it's like to have multiples :)
