congrats on your son and starting him on EASY early on. My questions to you is do you pat/shush all the way until he is asleep? The idea being that you pat/shush to get them calm, esp. when they are a newborm, and to help them fall asleep in the crib from an awake state. As they get older though, you are supposed to back off the pat/shush so that they don't need it to fall asleep. So you would gradually decrease it and maybe just keep a firm hand on them, and then eventually just a few pats and leave them be to settle themself-but of course intervene if the need you.
pat/shush is great to soothe with young babies since they can't soothe themselves. But as babies get older and can learn to start soothing themselves, you want to take it away gradually.
so...with that being said, if you have always pat/shushed all the way into deep sleep, then perhaps it has become a prop?
