It shouldn’t come as a surprise that a soothing, calm tone of voice is something that your baby will be able to pick up on, so whenever you’re trying to get your baby to bed, you’ll want to use this kind of voice. Speak softly, as if you were trying to reassure your child that everything is OK; this is especially true if they tend to cry and fuss when you’re trying to get them to go down for a nap. This alone will go a long way towards getting your baby to sleep, so even when you’re feeling frustrated by your baby’s behavior, stay calm, cool and collected and keep soothing your baby with your voice.
