All my kids co-slept with us so it was a difficult transition. I currently have a just turned 3 yr old, 6 and 8 and all were trained same way. bath, brush teeth, pick up rooms(for bigs), pick an sleeping buddy(stuffed animal or toy car for my boys), in bed and hugs/kiss goodnight. For the 3 yr old, I used to have to lay down and cuddle till he fell asleep, now he just goes in and sleeps. Thank God as I have a good 3-4 hrs to get stuff done. Sometimes you let them cry it out but always go back to bed, never back in OUR bed or they get used to it. Oh and all the givens as said above, potty, sometimes read a book, but my kids like to read out loud to me while I fix breakfast or they read to their baby brother. We’re in bed by 8-8:30 and up by 6:30 as bus arrived 7:20. Also no food/drink an hour before bc I dealt with lots of bed wetting w/all my kids.
