My boys are 21 months apart and the tips above are great...
Not sure I have much more to add.. though DH was always v involved with DS1 I think one of the major things is that Dads often have to do a lot more and have that 1:1 time withthe toddler - its a great thing but make sure DH is prepared for it. it was ok for us, he spent a lot of time anyway but i know a lot of families where it was a shock to the system.
One of the hardest things for me is i felt more hjomebound with no 2. we were rarely able to do something as a whole family as someone always needed to sleep - until DS2 went to 1 sleep.
