Your child is learning how the world works by playing and exploring. Through play, infants and toddlers learn about how things work and how to be good problem solvers. The last time my grandson was here for lunch, I gave him a hard boiled egg and an plastic egg slicer. It only took a few moments for him to figure out how to slice his egg. After his accomplishment, I complimented him on how he problem solved before enjoying the newly sliced egg.
