Some of my daughter's favorites at this age were:
Brown Bear, Brown Bear, What do you see? By Eric Carle (also Polar Bear, Polar Bear, What do you Hear?)
Doggies by Sandra Boynton
Baby's First Words by Roger Priddy (I would highly recommend any of the Roger Priddy "Bright Baby" book collection- they really teach baby all sorts of new words)
Go Dog Go! By P.D. Eastman
Winter Friends by Carl Sams and Jean Stoick
Any book where you have to lift flaps!
Good Luck- I hope these suggestions help!
