Having parented several 13 month olds before, let me fill you in on the wonders of a child that has done much self care prior to arriving in my home. This 13 month old can CLIMB. She can open containers. She can flush the toilet. She can open doors and navigate stairs. All told that makes her a dog's best friend. He even wants to supervise her bath, and has jumped in more than once.
And all day, every day you will hear me say ... "NO! BABY that is PUPPY food!" followed by ... "TRIP!!! Put down that toy! Baby's Toy!"
BOTH OF YOU, QUIT PLAYING IN THE TOILET!!!
