We did the same and she didn’t seem to mind the sucker too much
I used the frida too! I didn’t have saline at the time but I dropped in a bit of my breast milk into my daughters nostril and it helped a lot
Surprisingly yummy time helped too! Because of gravity, the snot was reaching the tip of the nostril and I was able to pull it out haha
We used the snot sucker by Frida brand and saline spray (Fess) had to use it a couple times a night to help him sleep better and especially early in the morning.
