Sleep training tends to punish babies and toddlers for problems that don't belong to them. They are left to cry, put down while they still need a hug, denied milk when they are hungry and ignored when they most need comfort. I don't actually believe any parent wants this for their children, yet their exhaustion leaves them with no other choice. Or so they think
It's one o'clock in the morning and your son, or daughter, is bouncing up and down on the bed, grinning and giggling at you. In their world it's playtime. No matter how hard you encourage them to sleep it's just not happening. An hour or two later they finally wind-down and drift off to sleep, before waking for the day shortly after.
