My 17 month old grandson absolutely loves everything about his 1st My First Book. I bought the farm animal one and he loved the box, the bag and especially the backpack, before he ever even saw the book!! He walked around with his “moo pack-pack” on carrying the box for hours, then finally got to the book and he adores it!! So many activities within the book!! I’ll definitely be making additional purchases for not only this lil guy, but the new grand coming in March.
