We never sleep trained our 3yo but finally started to teach her to sleep on her own using the method taught in The Happy Sleeper book. Now we no longer lay next to her until she falls asleep (yay!); we check in on her in 1,2,3,5,10 minute increments at her door. My husband is usually in charge of her sleep but tonight I decided to try it for the first time. He warned me, “she will ask you to lay with her, don’t do it” and I was like yeah sure of course. After the 5 min check in my daughter goes “mommy? You need to come closer to me…because I love you.” 
how do you say no to that? Lol. I said, “ok baby I’m going to brush my teeth.” She goes, “okay, go quickly mommy!”
I brushed and by the time I was out, she was asleep. Not sure if I was happy she fell asleep on her own, or disappointed I didn’t get to cuddle.
