If your baby is still unsettled after checking whether they are hungry, cold or hot, needs changing or tired and just wants a cuddle you could try some of the following;
Babies love to hear your voice so try talking to your baby.
Babies love gentle rhythum so try rocking them. Patting him may also help to soothe. Its thought a gentle patting noise will remind your baby of your heartbeat.
Make shushing noises, or other white noise such as the hairdryer, will remind your baby of being in the womb.
Wrap them up and hold them tight, keeping your baby snug just like when they were in the womb will reassure and settle your baby.
Try baby massage a great way of forming a bond and closeness with your baby.
Take a drive. Driving around the block combines steady motion and white noise. If driving isn't convenient, try a vibrating bouncy seat or swing, which also have the white-noise/movement combo.
Many mums swear by baths to calm their babies. The sound of the running water and the warmth on the skin can do wonders for a crying baby. You can get into the tub, too, to add soothing skin-to-skin contact.
Distract your baby. Introduce a new toy or shift his attention to the family pet or a mirror (so they can gaze at themself). They may well forget all about their cranky mood.
ALWAYS keep your cool. If you get frustrated, your infant will pick up on that tension and react, and this pattern can become a cycle that's hard to break. Trying too hard to calm your baby can also backfire - some simply don't like to be handled as much as others. While you shouldn't let infants under 3 months cry it out, it's okay to let them fuss for five minutes. This will give yours the opportunity to start to figure out how to soothe them self (and it may give you a chance to regroup, too).
Keep your baby close for comfort, lie your baby on your chest or hold them over your shoulder, they will enjoy seeing the world from a different angle. Your baby will also enjoy sucking so offer your breast, bottle or pacifier.
Never hesitate to consult medical advice if you are unable to calm your baby once you have addressed all the common concerns as listed above. When a baby cries, it triggers the release of the hormone prolactin (dubbed "the mothering hormone") in moms, which creates an urge to pick up the baby and meet their needs. You're hardwired to soothe your baby, and when that doesn't happen, it can make you feel like a failure. But your baby's fussiness is not a reflection on your parenting skills - and it's completely normal for a baby to cry even when there doesn't seem to be a direct cause. If you're ever in doubt, however, don't hesitate to call your paediatrician to make sure there isn't an underlying problem.
