Growth spurt??? 3 week 3 day old newborn

I was pretty sure she was going through a growth spurt last week @ 2 weeks old as she was only going about 1.5 hours between feeds for about four nights.

She gave us a few nights this week where she slept in two 3 hour chunks, followed by two 1 hour chunks. Totally thought the growth spurt was over.

Until tonight. She’s been up every 1-1.5 hours from 1030pm onward. It’s 330am and I’m on my 3rd feeding.

Please tell me this ends at some point.
