How many naps is your baby taking a day?

My 6 month old has decided she only needs one 1-2 hour nap a day. Before this she was taking 2-3 40 minute naps a day. I have read all the books, all the blog posts, talked to a sleep consultant. Nothing works. She sleeps all night and is fairly happy during the day so I’m guessing she just doesn’t need the day sleep??
