Re: Anyone else...
It took me quite a long time and only after baby #2. To get a good tight fit try pulling up on the wings before folding across the front while simultaneously keeping a good tight hold of the front part of the diaper. So rather than pulling to the side on the wings, pull up and over. Wish I could do a video tute but that was key to figuring out how to prevent the diaper from falling off after putting it on the baby.
That said, aside from the side-pinned angel wing fold I never could figure out how to get a tight fit with actual pins. I can snappi, but not pin (and for some reason not boingos either, I always end up with cut fingers with the boingos).
