Bed time and nap time rituals

Cindy • 25 yo. FTM to a Baby girl. Grace Elena<3
My daughter will be 4 months next week and I made the mistake of getting my daughter used to only falling asleep while us laying down to breast feed. Now it's Almost impossible for me to get her to sleep more than 5 mins any other way! Might I add she still sleeps in bed with us. :/ Anyone have any advice?! do u guys really think showering at night helps more? I start work soon and don't want my mom to struggle! We have such a hard time getting her to sleep. She sleeps fine in our arms but once we put her down. BOOM, she awakens 5 mins later :/ I'm getting desperate.
