A few months ago I went on a search for those baby disposable placemats that I used to buy when Kaden was little and I found this.
Kiddopotamus Portable Place Mat
This was a great investment. Suction cups keep this table topper in place on most tables. Includes a scoop to catch the mess.
It is also a good space saver. Just fold in the sides, roll it up and tuck into the scoop.
I paid around $9.00 for it. It can be found on the Toysrus, Target, and Walmart Websites. Comes in 4 cute colors blue, green, pink and yellow.
