Mother's Ring.

The stackable rings are a great idea. I know someone with them and hers are quite nice. Vary the shapes and it really adds a special touch

my boyfriend got me a mothers ring for xmas two years ago and if we have another one i will probably get one similar and wear it on a different finger and maybe get a necklace with both of their stones in it. i would personally rather have a ring for each kid and then get something with all the kids birthstones/names on it

I found a Mother's ring stuffed into our Christmas tree the first Christmas after our daughter was born. Santa has my birthstone, then my daughters birthstone, and then diamond place holder stones that can be replaced with future children's stones. As you can imagine I LOVE it. The Christmas I turned 16, my parents had Daughter's rings made for me and my 2 sisters. They each had our birthstone in the middle surrounded by my parents birthstones. It still remains one of my most treasured pieces of jewelery. I will do the same for my daughters when then turn 16.

I like limogesjewelry.com They have some cool stuff. They actually have some cute ones at walmart.com I like. You can find affordable mom's rings. I plan on having more kids but it won't be until I'm out of college and all that so I'm getting one now and will get another one later if I have to :D

You can also get the stackable rings where one child per ring. I love those rings.

For my first Mother's Day my husband gave me a small band with 5 stones on it. Our son was born in July, so the stones were Ruby, Diamond, Ruby, Diamond, Ruby. We now have two boys and think we're done. So, I'd like to change it two our 4 birth stones and a diamond in the middle. No idea how much that would cost, but that's my current plan.

We gave my MIL a Cross necklace to wear that has the current 3 grand babies and it has white or clear stones in place of all the others to come.....or not. (Which ever God allows). I have thought about that too myself. I like the idea of the ones that you can add as you go along. If you want one now...by all means - why not?

Some other options are a necklace or bracelet with independant charms that can be added or changed out to get different styles and add children as they are born.

I woud wait for the mother's ring until I was done having kids becaue it may mess up the ring if they took it apart to add stones. Even if they are all born in the same month they each get their own stone.

A mothers ring is a very nice mothers day gift.

We gave my mom 2 mother's rings. One with all of our stones (5 total) and one with three stones (just us kids). We gave them to her when she was done having kids. Not sure why, just what we did in our family.
They have some that have stones inbetween where you can easily swap out for another child's birthstone if you have more. They also have some that have multiple bands. It's sort of like how your engagement and wedding ring are supposed to fit together (kind of hard to explain). Each band has a stone for each child (3 children = 3 bands, etc).
Good Luck.

Google stackable birthstone rings. You just add a new ring everytime you have a child...

The mother's ring I have has three stones (one for me, one for hubby, and both my boys are February birthdays, so one stone for them)....It basically goes like this....my stone....CZ "filler" stone....larger stone in center is my sons' stone......CZ "filler" stone.....hubby's stone. This was a huge selling point for me because we can easily drop the CZ stone to add any additional stones. Its a family ring style, so it has a few more stone options in it.

Personally, I'm waiting until I'm done having babies.
