Toys that are considered to be best are the ones that can entertain and encourage your baby to explore, engage and interact.
I listed here below toys that are best for your baby under 1 year, for your choice :
1) Manhattan Toy Winkel
2) LeapFrog My Pal Scout
3) Cloud b Sleep Sheep Four Soothing Sounds From Nature
