I'm a dad of twin girls too. The only advice you're going to need for the first two years is "don't worry, it does get easier". After that it becomes insanely fun and much easier than parenting just one as they have each other to keep amused.

Ha. You wouldn’t be happy with that purchase for the first two years, that bit is a living hell.
