TWINS!!!

Laura
I'm in the middle of a little melt down, just been for a scan since I had a little bleeding last week and everything looks fine however I have 2 in there!!! 
This will make #4 and #5 my youngest is 15 months at the moment so will be just under 2 when these guys make an appearance and I have no idea how I will cope with 2 babies and a toddler plus 2 school age children!! I only have 2 hands!!! 
Anyone have any advice for twins? From whether I'm supposed to double my folic acid intake to how to juggle sleeping and feeding in 9 months time?
