My 2 are 3.5 years apart. We do bath together at about 6:15pm and PJs right after. DD (2yrs) goes to bed at 7ish and DS (5yrs) goes to bed at 7:30. After PJs, DS gets some TV time before going upstairs at 7:30 to do stories, while DD is pretty well headed straight to bed after bath. We basically just tag team it - DH takes ones and I take the other. If it's a solo-parent night then we do DD first and DS second.
