Hi Susan,
For what it's worth, here is my routine (12 week old twins), which we had from about 8 or 9 weeks onwards. Please note that the sleep times are targets, as surprise surprise the twins don't always do what mummy or the book has in mind ;)
I feed them one after the other, btw. They are bottlefed.
6/7 feed
playtime, ca 1 hour nap downstairs (they sleep very differently, so my DS normally sleeps much less than my DD)
10/11 feed
2 1/2 hour sleep in nursery
2/3 feed
playtime, ca 1 hour nap downstairs
5:30 bath (sometimes I bath both together, sometimes one first and then the other just before her feed, depending on whether my DH is around to help)
6/7 feed
10/11 feed
currently waking up around 3 and 4 respectively, just settling them with dummy (no idea if this is right, but I have another thread to ask for advice on this).
