I think you ladies are very generous.
I dont think you need to spend more than $20.00. It really is the thought that counts. I used to have a day home and I I think that $20.00 is more than enought.
If you want to spend more than I know they will love it.
I think any of what you ladies have mentioned are all great gifts.
Do they drink coffee? Perhaps a basket with some coffee stuff....mug, coffee, pretty spoon?
I like the soap and lotion idea...specially when around kids...you should be washing lots thru out the day.
Look in their house....do they like candles? Do they collect anything?
OOOHHH OH another thing I love to gift with is the willow tree ornaments
http://www.demdaco.com/willowtree.aspxThey are very personal and simple. I think the "thank you" one is nice...."mi casa" if you look at it like
you house is my house....because your kids are there. There is one called "greatful". Even the "guardian angel" cause they care for your kids. "angel of wonder" working with kids keeps you wondering? perhaps. Just some ideas.
did I mention that I love these ornaments. LOL
Those are a few of my ideas.
good luck
