Yep - dd (2.3) is like this lately! Annoying isn't it?! However as long as there's enough interesting activities/distractions throughout the day we're fine.... I have yet to capitulate! I've found that what she normally means when she asks to go home is just that she's bored/had enough of the current activity so it's time to move on to something else.... Probably just lack the imagination/mental resource at this age to suggest anything other than that which they're most familiar with??
