It's normal to feel this way as you didn't have any experience.. Nanny are use to and know what they wan just by reading thier cries. Maybe u like to research more on baby crying. Normally baby cry is either they are hungry, feed them, wet diapers, change them, wind in the tummy, apply oil to release wind everyday without fail after body cleaning or bath, or didn't burp them properly, sleeping time, don't over stimulate them. Talking to baby when they cry is useful too. I seen mothers keeping quite didtn talk to baby to sooth them in the end the baby cry more in the train or public. Ask ur nanny many question about baby, ask her for tips to sooth baby too.. They will defdinateoy teach u. And most importantly don't panic when baby cry, they sense ur worries and cry even louder. Using lavender essential oil to diffuse in the room to calm them is another way. So they will not be a fussy baby
