Of course you can get pretty much the same things for your mother-in-law as you do for your mother, however, I think there is a different relationship there. My mom and MIL are quite different and obviously I don't know my MIL as well as I know my own mom so here are a few things I think my MIL would personally like as well as (hopefully) any mom!
Again, giving her own spa is always appreciated. Would doesn't like to relax and enjoy a bubble bath? I'm not a regular bath taker but when I have things to make it more special I am ready to take the plunge!
I think these little everyday things are really sweet and it will remind her everyday you care about her. If you include the atomizer with a scent you think she will like, all the better!
Again, at first I didn't think I would like slippers but now I don't know how I got along without them! I think anyone, mom or dad would really like these.
I think a lot of women like to carry a lot of small items in their purses so why not give her something cute to carry them all in?
This necklace is so sweet and not too big but if you personalized it with her child's initial on it will mean just that much more.
Finally, I got this set for my mom for her Easter basket and she really liked it! I think a lot of moms would like a little purse pampering!
What are you getting your significant other's mom for mothers day? Do you have any suggestions? Let me know in a comment!
