I did only flats and Flips from 3-12 months with dd. Unfortunately, when she started climbing and riding on toys and being an all around toddler the flats starts bunching in the middle horribly and I was having issues with her peeing straight out the side as a result. So I'm back to stuffing my pockets with flats and pinning prefolds. Hopefully it will work longer for you. It was my absolute favorite diaper ever! I wish it was still working for us, it was such an easy combo.
