Here it is.  The design that started it all.  This was one of our first two designs, along with A is for Algorithm.  I no longer remember which came first.  We aren't making a statement about breast feeding vs. formula (believe it or not this design has caused some controversy).  It's just a statement about how me we love Math!

If you need a baby gift for anyone into math, this is it!  Don't forget I Like Formula is also available for adults!
