A typical babymomma dilemma

When the kiddiwinkles are scrumbly and having a wobbly is it better that they do it at the same time, so the total wobbly duration is shorter and hopefully they are both exhausted at the same time later and babymomma gets a much longed for and deserved break; or is it better that they take turns - which might mean wobblies are being thrown for a longer amount of time but at least babymomma feels she can deal with each more effectively?
