I did follow the routine but mine is AESY. I tried easy but bb was too hungry by sleeping time.
I find that with a routine, everything is easier . Yes I swaddled my baby from birth till 6 mo. Swaddling is part of the sleep routine. I swaddled baby , feed , burp , pat to zzz.
No matter what routine or method, most important is consistency. Every day is the same , meaning for the initial days, I minimise going out. When it's time to sleep, I m at home.
