A mother is happiest when she is 
near her children. So it is her children that makes a happy mother. And I
 can say this is true of all the mothers I know, especially my mother 
and my mother-in-law.
The moment a child is born, a 
mother is born too. A mother's world revolves around her children. As 
long as they are with her, she has something to look forward to 
everyday. Taking care of her kids, making them their favourite meals, 
washing their clothes, tidying up their stuff and rooms, cleaning up 
after them, playing and spending all her time with them is what she 
knows best.
A mother who has grown up kids, who
 do not live within her proximity, is never truly happy. Although she 
has now more time for herself, she prefers spending it in thoughts 
directed towards her children. All day long she wonders what her child 
is up to, what he/she is eating, whether he/she is sleeping well, taking
 care of themselves. She mentally keeps count of the number of days 
before she could see them again. She waits for their call, and when it 
does not come, she does not hesitate to call them herself. She longs to 
know how her child is doing without her. She loves to know that her 
child still needs her and her advice.
A mother is usually always worried;
 worried about her children's well being. She is worried when her child 
is playing, sick or travelling, when he/she is writing exams, on job, 
staying away from home, seeing someone, getting married, having kids and
 hence worried all the time.
A mother has some advice on 
everything under the sun. As Harriet Beecher Stowe rightly quoted, "Most
 mothers are instinctive philosophers". We might complain as much as we 
want, but it is true that we can not do without her advice either.
A mother misses her children 
whenever they are not around. When they are not home, she prefers not to
 prepare their favourite dishes. And when they are home, she gives up 
her share so that they can have more. Tenneva Jordan correctly quoted,"A
 mother is a person who seeing there are only four pieces of pie for 
five people, promptly announces she never did care for a pie".
A mother is happy when her children
 are near her, but she is happier when she knows that her children cares
 for her and loves her too. As children it is important for us to show 
her that we care, in whatever way possible. It is our solemn duty and 
responsibility to take care of our mother's needs. However, we might get
 her any material thing, but it is our time and love she needs most. She
 needs our heartfelt care, sweet words and unconditional love.
So next time you wonder what makes 
your mother happy, just remember that it is you who makes her happy, 
happier and the happiest.
