Did your milk supply vary with different babies?

Currently 20 weeks pregnant with my 2nd baby.

My first was born early at 32weeks due to preeclampsia and despite my best efforts I could never increase my supply (she also tired very easily and didn’t latch properly, which we later found out could have been due to laryngomylacia).

Since about 13weeks this time around I have been having a tiny amount of dried colostrum on my nipples. Is this a sign that my supply will be better this time around? Has anyone else struggled with supply for their first but been ok for later babies?

Just curious as last time was very stressful with hospital stays and pumping continuously to them feel like a failure in the end!
