People were always amazed at how our kids went to bed with no problems. In that spirit I offer what worked for us which may not work for anyone else. First we limited nap time. Second we did the exact same routine every night. Rocking and a bottle then bed. When they got bigger it was rocking, reading some books, bottle then bed. Then we added in teeth brushing. Every night same thing. Bed time was lights out (with night light) and stay in bed if you need anything holler. I’d go back a few times for “I’m hot/cold can’t sleep” then they’re out. Wake up same time every day. I love routine so it’s easy for me. Others may struggle.
