How to get my kid to play with her toys for longer?

if your child is still young, the attention span will be shorter and that's pretty normal, and more so if a child is active and wanna explore everything. I suggest you stop buying toys, unless it's one that can spark creativity, focus, problem solving. otherwise, a child can also learn much but playing with household items, or going outdoors more. keep the toys in boxes and rotate the boxes weekly so that it seems like there are always new and different toys. hope it helps!
