Baby's feeding habits

Susan • Peyton Louise Jones was born 16th June 2016...Kalen Jones 22nd may 2020
Over the last 3 days my baby girl has completely changed her feeding habit, she is 4 weeks and 3 days weighing nearly 11lbs
So she eats 4-4.5 ounces and hour later she is crying and fussy and wants another ounce and then calms down and then wants entertaining for an hour and then falls asleep for one hour and then wakes up for her 4-4.5 ounces again and follows the same routine, it's getting tiring.
Is this her growth spurt does anyone know? If so does it last long? Or is she just going to be like this for a while? 
Since it has been the weekend my partner has been here, but I am dreading tomorrow on my own, I am going to be stressed
