Got Water....and a straw...

My two little guys, hated to drink anything other that milk...it was a constant struggle in my home. They eat tons of fresh fruit and veggies, so I am OK with them not drinking juice but was about out of my mind trying to get them to drink water. FINALLY I thought.... if I put it in a fun CUP will that help? We play outside alot right now, so I get down 2 spill proof sippy cups with a STRAW instead of a SPOUT... and said " these will ONLY ever have WATER and never anything else..." This is all they can have while outside... We gave the boys their new cups and held our breaths... they LOVE them... my boys have been straw sippin water drinking fools for 3 days...hehee.....
