This was my fav Dr Seuss growing up. It doesn't really have a plot, but is a collection of drawings of "beasts" with rhyming verse to pull it all together: "From near to far, from here to there, funny things are everywhere". I think the appeal is that it is very friendly to children's imaginations, not being at all prescriptive - the child can imagine the how, why, what next of each creature. I used to love picking favourites.
Reading it to my 5 month old daughter is a success. We have the anniversary edition hard cover, so she is interested in the shimmery gold reflective surface as soon as I pick it up. The rhymes are short, so we crack through each page at a good pace. There are lots of chances for silly voices - and she turns to me in amazement each time I change my expression. It is easy to keep her attention, easier than the "cat in the hat" books, which are too long and wordy for this age. All the creatures are different so each page turn brings something different. She tries to pick up the picture on each page.
All up - a winner:
I enjoy reading it and it is suitable for 5 months.
