Cosleepers are great until baby gets a routine, since they're just right there. But once they start sleeping longer stretches at night, I liked having a separate room so that DH and I could trade off feedings. But I also know women who still cosleep with toddlers...whatever works. I would think you'd still want a nursery to store all their crap and have a changing table and diaper pail, no? It's funny, our first is a boy so we have mostly blue stuff already, so if it's a girl, she's going to see a whole lot of blue!
My NT scan is next Wednesday. I debated doing it at all since it can be stressful and the results wouldn't change anything, but I found out it is covered by insurance, so why not take a peek at those cute feet?
