4 month sleep regression??

Rebecca
Anyone else suffering with this dreadful sleep pattern that just reared its ugly head at 4 months?? My baby boy started waking up every 45 minutes throughout the night. Some mornings wants to wake up at 5am, refuses to nap during the day, if he does nap it's only for 10 min. Anyone else going through this or have any advice?? 
Sincerely,
One Tired Mama 😩😴
