I am the oldest of seven. Without realizing it, I learned how to get a baby to go to sleep from my mom.
I had five children in seven years. The first two were fourteen months apart. After each one had been fed I put her, or him, in the baby basket wrapped in a baby blanket. I gave the babies a pacifier. When I checked on the baby few minutes later they'd be asleep. If they woke up again I'd check for a wet diaper and do the same thing. Buy two months they didn't want the pacifer. I moved them into a crib and covered them with a blanket. None of them ever fussed about going to sleep. When one of the daughters crawled out of bed. She would go to the stairs and slide down on her belly. We never heard her. She just stood in the doorway. When we finally did see her we'd take her back upstairs, give her a kiss goodnight and put her back to bed. Then I sat at the top of the stairs where she could see me. Eventially she laid down and went to sleep.
