Before 10 months, he slept in his baby bed; but the baby bed also next to me and my hub. After 10 months, he starts to sleep with us, till now, 3 years old, it is the same.
My son is 18 months now,he sleeps with me and his dad before, I just train him to sleep in his room. But, He wakes up about two times every night and he will cry when he notices he is alone. Then I need to let him sleep on his bed again so that I can get back to sleep.
