How it started

I was expecting our first daughter and I was dreading changing diapers.  I told my friends that I was going to potty train her as soon as possible.  Naturally they thought I was crazy.  My little girl was born and I started changing her diaper.  “Hey, this isn’t so bad”, I told myself.  At a week old, her poop spilled out of her diaper.  The diaper must’ve been loose, I thought.  A few days later, it happened again, and then again.  I found out this was a common problem and people solved it by using larger diapers or stuffing an additional diaper or tampax into the diaper.  It sounded ridiculous.  After being sprayed with pee a few times during diaper changes, I concluded that I had to potty train my little girl asap.  This is when I found elimination communication.  And I started practicing with a plastic bucket.  My wife thought I was crazy until I caught our little girl’s first poop.  We were both amazed.  But it was a two-man job and my wife refused to try it fearing that she’ll drop our little girl. 


I thought that I could probably make an apparatus that safely holds her and positions her to poop.  I woke up every day at 5:30am for my day job, got home at 7pm at night and worked on the prototype until 2am.


After many prototypes and iterations, the EC Seat you see today was born.  I still remember the days when I was grinding and sanding and fiberglassing in full coveralls, respirator and ear protection in the unheated garage with the garage door half open.  I remember there were days when it’d be snowing in the morning, sunny in the afternoon, and raining in the evening.  I remember questioning myself several times why I had quit my engineering job to work in a garage.  But the thought that this was for my children and it was to create a better future for them reaffirmed me and kept me going.  I traveled alone as far as I can.


I knew I was challenging the 46.5 billion dollar diaper industry.  I knew they can crush me like a bug but I still wanted to pursue this because it was the right thing to do for the world and for our children.
