Help calculating calories! please

Hi all,

Just wondering if I could get some assistance as to how many calories i should eat a day. Right now MFP set me at 1240 but I'm ALWAYS starving and i try my best to eat healthy, filling meals. Any advice would be appreciated. Here are my numbers:

Height: 5 feet
Weight: 160lbs
Activity level: I do 30DS everyday and run after 2 kids all day, not much but all I can fit in
Age: 25

Thanks!!
