I give cards and presents to both my mom and MIL.
I get cards from both and sometimes presents from his mom, too! I also get cards and presents from DH and both kids.
We're really a card- and present-giving family!! Hallmark loves us!! For example, Mother's Day:
1 card from us to my mom
1 card from my kids to my mom
2 cards from us to his mom (1 sweet and 1 funny)
1 card from my kids to his mom
2 cards from DH to me
1 card from DS to me
1 card from DD to me
9 total....minimum!! DH often finds too many he likes and gets 3 or 4 instead of stopping at 2

They're usually funny ones but he writes sweet messages inside them all!!
BUT, I know some folks who just do one card from the kid to the mom and that's it. Just depends what's tradition in your family!! I know when I was little I gave my aunt a card on mother's day....she took care of me every day after school, took me to scouts, choir, violin lessons, etc. since my mom was working (aunt was a teacher at my school and I never would have been able to do anything without her making it possible)! I was giving her cards and altering them to say "like a mother to me" before they made cards for all these different situations
