You will have the most luck doing a circle time with songs and fingerplays - think Itsy Bitsy Spider and Slippery Fish and Zoom Zoom Zoom. They will love it and stay engaged and learn actions and songs.

For story time at that age - it is better to take them one by one or two at a time on your lap for a board book. They won't last through something long. Something about Dora or Alligator Pie, Going on a Bear Hunt with the actions etc will be fun for them and they will love it.
