A lot of parents seem to worry about their young kids being stimulated, but I think a lot of young kids are over stimulated. Babies, toddlers and young kids need time to play alone and need quiet. For babies that might mean playing with their toes happily, or just sitting there burbling away happily to themselves. For toddlers playing with a toy, or looking at things on a walk. You also see it in parents who talk constantly. Toddlers being followed around by usually mums as the mum constantly talks to their child, asks questions and comments on what the child is doing. There is no silence, no chance for the child just to bumble about doing nothing much.
