My 27 month old likes to be swaddled when awake and rocked when she feels stressed. She was swaddled until she was 19 months or so. In my husband's home country, children are swaddled until they outgrow their cribs, which is usually around 24 - 30 months.
I think the whole country is generally under-swaddled, personally, and that more swaddling, proper swaddling with an understanding that they occasionally cry a bit at first, would solve a lot of sleep problems. Not all, of course, but some.
It's not that the stay-at-home-parent gets to stay home with the kids. The kids get to stay home with a parent. Lucky Mom to DD1 (4 y) and DD2 (18 mo), Wife to Mercenary Dad
