Bbo, you and nanny agree on the young schedule, it was me that didn't understand what she said. I was thinking I could do it at start. She clarified it for me in the post just above yours.
Just to be clear, I do not let him sleep on his tummy. As soon as he nods off, I pick him up and move him. Tummy sleeping scares me!!! I just mentioned it because so many have talked about how their kids hated tummy time.
