• Have a solid bedtime routine. Experts say that regardless of which sleep-training method you use, having a stable bedtime—between 5:30 and 7:30 p.m. for infants, Vance suggests—and a steady routine are key. Whether it’s bath, book, lullaby, bed or a different sequence, doing the same thing every evening is part of the bedrock of good sleep hygiene. Blackout curtains and a white noise app may also help.
• Chair method. Also called the sleep lady shuffle or gradual withdrawal and popularized by Kim West, LCSW-C, author of Good Night, Sleep Tight, this method starts with you sitting in a chair next to baby’s crib. Each night, you move the chair farther away from the crib, verbally soothing or shushing baby when she cries (although occasional patting and picking up are okay) until you’re no longer in the room. This method can be helpful for older babies and toddlers who may suffer from separation anxiety and can understand that Mom and Dad are just on the other side of the door, but it also works for younger babies.
