I personally don't need a rattle! I don't even know if babies really get entertain by the subtle noise. However, when I saw this little yellow bunny, I told my husband that our baby would be for sure much smarter if he could play with such a delightful toy! Um um, he said. I must admit that my argument was poor but look at it...it is ssssooooo cute!
Instead, since I'm a responsible mother in progress, I got some baby leg warmers / crawler covers. I read that they are wonderful when it is your turn to do the diaper change.
