This is EXACTLY what we did and it works AWESOME!! Newborn: Sleeping Through the Night! - to get your baby to sleep 8 hours through the night at 8 weeks and 12 hours at 12 weeks. Basically BabyWise but she breaks it down so you don't have to read the book. This stuff works!! Getting your baby to sleep is totally a science.
If I knew about this sooner, I would have bought it for sure. Looks like the perfect thing for the littlest ones... and it grows with the baby... they can use it as a regular beanbag chair. So cozy and cute.
