I used small and large beans as a base, added heart confetti, red pompoms, large and small glitter balls, several heart boxes, fake roses and window gel stickers. I usually add extras gradually, when Kitten gets tired of playing with basic stuff. She liked beans the best.
Scooping and transferring big balls to little cups was a hit as well.
We also discussed the concepts soft/hard and fluffy/smooth/rough, arranged flowers and even learned letters "O" and "X" (same as "H" in Russian). She kept saying "h" holding a letter "X" and would find an "O" when asked, I guess we should move onto learning letters ;)
