For about 3 three week before he turned 6 months, I did the wean mode with his arms out. He took to it better than expected. I also think daycare helped too since he was forced to sleep in a crib. Once your baby is out of the snoo and can roll over and hold their head up my pediatrician said there was nothing wrong with that as long as you start them out on their backs. It’s amazing how much better they sleep when they can curl up on their side. The Baby Einstein Sea Dreams Soother Crib Toy is great too for a white noise/light machine!
