Just like adults, some children are also naturally clumsier, while others seem to have co-ordination down to a fine art early on. While it’s perfectly normal for children to develop as individuals, at their own pace, your child should be able to do the following by age four:
Pour from a jug into a cup
Hold a crayon between his or her finger and thumb
Hop in one place, on one foot
Use eating utensils competently
Throw overhand (although aiming takes a lot longer to master)
Stack eight or more blocks up into a tower
If you really are worried that your child is developing a lot slower than his or her peers, then speak to your doctor. Either he or she will be able to set your mind at ease, or recommend you for further testing.
