Little ones sharing a bedroom?

Laura

We have two girls (4.5 and 1) and live in a three bedroom house Expecting #3 in January! All of our bedrooms are big enough to share but I am starting to get anxious about knowing how to arrange the kids and how to go about it. So far it has been so nice for them to have their own room. Older kid doesn’t nap but does sleep through the night. The 1 yr old does nap and wakes up once in the night and sleeps in later. In the past we have kept the baby in our room until 4 months.

Looking for experiences and suggestions!! Thanks for reading!
