Most people who look after their moms, if she is elderly, do it with things like giving cash for daily expenses and paying for household bills. Perhaps doing the cooking or buying them clothes and such. It's more of the attitude that if you take care of her with monetary means or necessities it would be sufficient or your "duty" is fulfilled. Sometime because hardship is inevitable when we lead our daily lives and have problems of our own, don't you think your mom knows or understands. Last thing she wants is to be a burden to anyone.
Younger kids, or teens with younger moms instead, tend to look for their moms in times of trouble or when they are depressed about things at home, in school, squabbles with schoolmates or neighborhood kids, a teen crush, etc. They see mom as the "go-to" person when they are facing such things. Mom is like this safe haven for advice or a healing touch to ease any pain. Then again if one made trouble, she's the last person you want to see because you never want to disappoint her.
So, mother's day comes around and it's the best opportunity to make a difference than the normal days that we see her on a daily basis. For those with older moms, it's that special thought, gift, gesture or personal time that you share to reminisce over life and joys of her being your mother that she will appreciate. Even if you give a personalized present, unique gift, travel cruise or a picnic in the park; it should be made as an occasion to celebrate rather than an obligation. Then see the smile on her face.
For those younger kids, appreciating mom with a mother's day poem or song would be a lovely thing. After all she doesn't expect you to go out and buy expensive jewelry. Of course dad can always chip in for the kids and get a nice bouquet of flowers for mom so the kids can feel that they got something to brighten mom's day. Followed, of course, with a great day of family time together. And NO house work for the day!
So when the day comes, remember, every mom out there is different but same in many ways. That being, she brought you into this world and loves you unconditionally. Governments have declared a day in the calender year just for mothers. Now all that's left is to put on that smile of yours, mother's day gift in hand or even without, and wish her Happy Mother's Day.
