Baby waking...

6 week old Baby waking up every 30-60 min. At night. He's not over sleeping during the day either. He won't sleep in bassinet or crib, so he sleeps in my arms worked like a charm he would sleep 3-4 hours, now not even that works. He eats every time too. After he finishes a boob he always is offered a second, then I have to wait 20-30 min before laying down so I'm only getting 30 minutes of sleep if that at a time. Second night He's done this, first night was worse I got barely two hours of sleep, luckily it was dh day off so he let me take a 3 hour long nap but tomorrow he works so I can't do that( I have a 4 year old)
