Physical Development of The Toddler

Chapter 11Page 290

2

Body Growth & Development

• Babies continue to grow quickly but not as quick as the first year

• Height & Weight• Toddler grow at different rates

• Due to environment & heredity

3

• Environment• Diet• Exercise• Health• Even emotions

• Heredity• Genes determine

height• Weight

4

Years One and Two

• Growth slows after first year• Most girls reach 53% of their adult height

by age 2• Boys usually reach 50% of their adult

height by 2

• Often true that a tall 2 year old will be a tall adult and vice versa

5

Age 2

• Slow and steady growth rate• Gain 2 – 3 inches and 6 pounds per year

• Girls continue until about 11• Boys until 13

6

Other Body Changes

• 24 months, head is ¼ of total height• Adult’s head is 1/10th.

• See charts on page 292 Figure 11-2

7

Bones & Teeth• Bones continue to become harder• Degree of ossification not the same throughout

the body• Due to cartilage, bones are more flexible and less

likely to break than an adult’s

• Fontanels (gap between skull bones, soft spots) are closed or almost closed

• Full set of deciduous teeth• See page 294 Figure 11-5

8

Fat & Muscle Tissue

• Fat deposits under skin decreases rapidly between 9 and 30 months

• Chubby baby becomes more slender

• Muscle development (the lengthening and thickening of muscles is slow during the toddler stage)

9

Motor Development

• Large muscle development (refers to the development of trunk, arm and leg– Crawling, walking, jumping, running

• (gross motor skills)

10

Walking

• Around 1st birthday may start walking unassisted

• Often girls walk before boys

• Pushing a baby to walk may not help and may hinder

11

Beginning Walkers

• Stand with feet wide apart• Turn their feet outward and flex knees• Walk on tiptoes• Irregular steps, lurches, and weaves• Tilted spine lead them to lean forward

12

Walking at Two Years

• May look like a run but it isn’t

• Rarely go around obstacles but over them

• Distraction leads to toddler falls

13

Running

• True running begins at 2 years of age

• Not skillful runners

• Tends to be awkward

• Can’t stop or start quickly

14

Jumping

• Moves arms backwards instead of using them to help the jump

15

Climbing

• As soon as they crawl or creep• Between 15 to 18 months

• Hold to railing or hands

• Don’t change feet until after 2nd birthday

16

Throwing & Catching

• Begin throwing by accident• Forget to hold on to object• Enjoy seeing object move through air

• Then start to throw on purpose• Begins at age 1• Throw from sitting position first and then

from standing position

17

Small-Muscle Development

• Hands, fingers (fine motor skills)

• Eye-hand coordination—what they see with the way they move their hands

• With time and experience, clumsy becomes more adept

18

• By end of first year, babies can hold objects between thumb and index finger

• 12 – 18 months holds spoon• Feed themselves and drink for themselves

19

12 – 18 Months

• Toddlers can:• Remove hat and socks• Insert large objects into holes• Turn pages of a book several at a time• Begin to fit objects together• Build a tower of 2 to 3 soft blocks

20

2 years

• Hit pegs with a hammer• Hold crayons and pencils• Cannot hold or write with a crayon or

pencil like an adult• By this age shows definite hand deference

(left vs right)

21

Summary

• Grow more slowly in second year than in first

• Toddler’s bones continue to harden• Fat deposits under skin decrease• Brain matures at a faster rate than other

body organs• Full set of baby teeth present shortly after

2 years

22

• Toddlers refine gross-motor skills (walking, climbing, and throwing)

• New skills emerge (running, jumping off objects, catching)

• Fine-motor skills depend on child’s level of eye-hand coordination

• Show definite hand deference by 2nd year

23

Activity

• Page 302• Do the questions 1 – 10• Put your name on the paper and turn them

in

24

Brochure

• Develop a brochure explaining toddlers’ motor skills

• Include information on the order of learning

• Explain actions used in walking, running, and jumping

25

Find Equipment

• Visit websites and find toys and equipment which will provide activities a toddler could manipulate and enjoy safely

• Print out product information and photos to share with the class
