Hi, we bought a Maclaren Techno Baby Carrier about 5 years ago in TKMaxx but never used with our DD. Our DS is now 1 month old and I'd really like to try it. But I know some carriers are meant to be bad for baby's hips, is this one? And if it's ok, does anyone have some instructions to it as we can't find ours and it just doesn't feel right!! Thank so much.
