Is that the entire question? Did you leave out anything?
 
Yes sir that is the exact question

Sorry I am being so bland and anxious, i only have a limited time

Well AFAIK, approximating the children as point masses, means that they can just be considered as point and the dimensions of the children don't matter. Not much can be done with the question if that is all the information given.
