jen,
I don leave the bowl on the floor, i will hold it,
at first i try on Sabrina, she can't even pick it up the beans , i see her face a bit "mang chang" and disappointed. then i says " never mind , try it again "
then keep the bean bowl , try it 2/3 hrs later. she has make to pick it up well.. hehe.
Do you know when i see her doing it , find then is not easy for bb to pick it up..
