If you have trouble getting your toddler or young child to go to sleep of a night, try this method: Gently but sternly (no yelling) settle them down; spend only a couple of minutes doing this. Then, quietly and without fuss, leave the room telling your child that you will be back in a few minutes. Wait 2 minutes and return, repeating the same settling and leaving routine. Wait 4 minutes and repeat. Keep doubling the wait time. You may find this doesn't work for a night or two, but soon the child will respond and settle more quickly; they'll enjoy Dad's 'tuck-in'.
