1)If you're thirsty and you can't talk yet...Find nearest supply of fresh clean water...Insert sleeve.
2)Try to be sly about it...if you don't look at Mommy or Daddy, they won't notice...
3)If they do see you, Give them that "what???" look and they'll be forgiving(and maybe grab the camera)
4)Then suck all the water from previously mentioned sleeve..
5)Repeat until thirst is satisfied!!!
and if anyone is thoroughly disgusted by this....the bowl was clean, the water was fresh...and well they must not have dogs!!
