Hi, this is Tom, and in this episode I'm going to be going through developmental milestones.

And you can find notes at zero to finals.com slash milestones or in the zero to finals pediatrics book.

So let's jump straight in.

Child developmental milestones can be separated into four major domains.

Gross motor, fine motor, language and personal and social.

A tom tip for you, the best way to learn developmental milestones is to play with children and test

their milestones. Try to find children who are developing normally at ages six months, one

year, 18 months, two years and three years. This will give you a good reference point

when assessing new children.

There will always be an element of rote learning, but it becomes easier when you can think back to a specific child at a specific age.

Let's start with the Gross Motor milestones.

Gross Motor refers to the child's development of large movements, such as sitting, standing,

walking and posture. Development in this area happens from the head downwards.

At around four months, they're able to support their head and keep it aligned with

their body. At six months, they can keep their trunk supported on their pelvis, for example

maintaining a sitting position, but often without the balance to sit unsupported at this stage.

At nine months, they should be able to sit unsupported at this stage. At nine months, they should be able to sit

unsupported. Children at nine months start crawling and they can keep their trunk and their

pelvis supported on their legs, for example maintaining a standing position, and bounce on their

legs when they're supported.

At 12 months, children can stand unsupported and they begin cruising, which means walking whilst holding onto furniture.

At 15 months, they can walk unaided.
