Hi there, my dd was exactly the same, it DOES improve, thats all I can say. Once she is able to hold and manipulate them, her interest should be engaged a little more, and she should be able to play for longer periods, but atm, I would ride it out, its probably just a phase, she is frustrated, and cant tell you why so vocally does so by crying... I would say things will improve
hth a little, I know how frustrating it is, but is does pass, hugs x
