It's funny you all have similar aged babies. Marisa was the same at that age. We'd be helplessly trying to read and relax her and all she wanted to do was run up and down the hallway turning the lights on and off! We'd bring her back to bed, but up she got everytime and I felt like the worst mother out having a daughter running the hallway at midnight!!! But she grew out of it Perhaps you could also try exhausting some energy before or after dinner, taking her to a park / playcentre or something where she can just run!!! But that big run of unsettled sleep quickly came to a halt with her telling us she was tired and wanted to be in bed around 2yrs.
