I've only tried it when she's sleepy but that was like twice. It gets so annoying to have on me all the time 😫

I did it by just getting him to latch without the shield. It's a slow process, but even if you can get a latch once that's a start, then continue to increase the amount of times you don't use the shield. I still use mine in the middle of the night when he's really fussy, as long as you and the baby are relaxed it should work for you
