Although a newborn baby's cries may sound the same to outsiders, parents will know their little ones have different noises to tell them different things.
But according to mum Anna Shields there are nine different types of cry - and she believes it's vital that mums, dads and other carers know the difference between them.
Taking to TikTok, Anna says getting familiar with these cries will allow you to "know exactly what your newborn needs" and claims understanding them is "life-changing".
