I waited 3 weeks before putting my son in it to sleep and the first night he slept 10 hours straight from 2-3 hours at a time! From there he increased to 12 hours a night and (2) 2 hour naps during the day. I tell everyone they must get one of these. It is my top baby pick. I just wish you sold it in mainstream stores so more parents could enjoy the wonder of sleep and a new baby. My almost 2 year old is now in his crib and still an excellent sleeper thanks to the amby. I\’m having my second child soon and can\’t wait to pull out my amby again. If you are unsure about this product just buy it! They resell on e-bay for almost the same price you can buy a new one. I have 5 friends that have also bought amby\’s and we all swear by it. I would suggest that the company get waterproof sheets to add to the product.
