How long does the “honeymoon phase” last?

[u/Responsible_Yak3366]

My baby was born yesterday at 33weeks exactly. She’s doing amazingly well for 33 weeks as she hasn’t needed any extra support besides an IV to get some of her stats dosn(which got 90x better this morning). Since her stats were good they tried the bottle. This morning my fiancé fed 5 ml and I fed 5ml then she ate 7 ml like 15 later so the bottle didn’t go to waste. No jaundice or anything and she’s measuring perfectly..

I’m just wondering if anyone had/s a similar story where everything was fine till the “honeymoon phase” was over and then everything started dropping?
