Booze, booze, and more booze.
Now that we got that out of the way – the best thing is to have a bedtime routine, saying Shma and Hamalach with the kids,reading a special bedtime story like Goodnight Moon, singing a special song to them… I always changed the last two line in Rockabye Baby for my kids, because I thought the originals were horrible. So I would sing, “When the bough breaks, the baby won’t fall,
Ki Hashem Elokeinu, Shomeir al hakol.”
My kids loved it, and now my daughter sings it to her daughter, and my granddaughter has even sung it back to me (she’s two, kinehora). Backrubs don’t hurt, either.
