This ladybug puzzle is one of Adrian's favorite puzzles - it is handmade with love from wood and ecological paint. A toddler learns size gradation, counting; and practices fine-motor skills. This puzzle can be introduced as early as at one year; we, however, introduced it at 17 months. At first, it was challenging for little fingers to fit the ladybugs in as they have to be position precisely due to its irregular shape. At 21 months, Adrian mastered the skill: he would insert them carefully tapping so that they fit, and he still enjoys this puzzle at two-and-a-half!
