Oooh... so need to do this! I need to shop tomorrow and get it done before the kids get home from school as there is no school Friday. Love that!
I'm so behind this year. I usually do MUCH more but, yikes, its been crazy lately.
This year DD is getting some American Girl sorta stuff. She's getting an American Girl book called Curbing Clutter (which I hope helps her with her room!), a homemade AG doll outfit, and two accessories that came from Walmart but are designed for AG sized dolls, a carrier that holds two dolls (she has one but is getting another for her birthday) and a high chair thing that attaches to the table. I'll throw in some candy as well.
For the boy... legos! I have a treo brand set (I think its treo?) that is a transformer. I got it free with a coupon.

Then there is another lego set that is a car track that I got on clearance for next to nothing (saved $11 on it!). He's getting a paper airplane book that one of the companies who pedal their wares at school had. I wasn't going to get it for him but the American Girl book for the girl was a last minute thing so I wanted to kind of keep things even. I was trying to entertain a little boy today at school after he finished his state assessment and waited for his class to finish up and I made paper airplanes with him. It was fun doing it with him, I figured I'd really love doing it with my son.
The bunny usually leaves a family basket in addition to personal baskets for the kids. This usually holds some big bags of candies and themed stuff like bunny shaped marshmallows or Easter pasta... a DVD, etc. Not sure at all what will be in that or if we'll even do that this year.
For inside eggs I have squinkies, little bottles of bubbles, erasers and little rings. I'll put in some candy and some coins (they love that) before we hide them.
Now and then the Easter Bunny will leave a basket for them to share. One year it was actually a gardening bucket (kind of like a wheel barrow only shaped differently) with all sorts of gardening tools for kids and outdoor stuff. Another year it was a big basket of board games. Those are the most fun for me.
I never spend much on these despite the fact that I kind of end up getting the kids a lot. I shop all year, use coupons, find sales, and get lots of stuff free (either through coupons or gift cards I get from swagbucks, superpoints, etc.)
