You can't go wrong with Dr Seuss
Format: Board book
Dr Seuss is always Just Right! This was a first Valentine's Day present for Thing 1 and Thing 2 (4 month old twins) even if Mom is still not so sure with my naming them but it kinda stuck before the gender reveal so there you go. The 4-year-old Big Bro will be reading it to the baby brothers in no time. The quality, size, low price for a hardback book to be read and read and read is perfect. It was so appropriate for the little dudes.
