I had a hard time right around 3 too...and I think it was because prior, she was really still a baby (although now I'm trying to see children as babies until 5, ala Crystal) and by three, I felt like she SHOULD know and be able to do what I was asking of her. I don't know, she just looked so much bigger then too. With a younger baby, I would say things a few times, simply because it takes a few times to 'get it' for them, but at 3 all of a sudden, it felt very permissive. I had to be more mindful of GOMB right away with dd. And now, with dd2, even though she is still much younger, I've started GOMB earlier. I don't know if it will make much of a difference simply because she is so little, but I figure it's good practice for me.
