He won't go to sleep!!

Leila
I feel like I'm losing my mind. Last night he slept for 4 hours today didn't take a nap and has been up all day.  I've been feeding and changing him all day. My husband feeds him the pumped milk I put in the fridge but it does no good. He's 2 weeks. I actually cried last night. What can I do?! When does it get better?!
