My one year old usually has her brothers to follow around and play with (they are 3 and 4). She is content to be with them all day. If they happen to not be home for some reason she will still play by herself for most of the time as long as she knows right where I am. If I change rooms she gets upset. I have an in-home daycare so all our rooms are child proofed and have toys so she just wanders happily wherever she pleases.
