Also, remember to return when you say you will. It is important for him to know you will be back and when. When introducing him to a new environment, take the time to let him get accustomed to his surroundings and the people or caregiver. Perhaps making short visits before actually dropping him off for an extended period. Before leaving your child with a new caregiver, bring along some items from home that are loved or familiar.
Many children have a lovey or transitional object.
Night time awakenings can be difficult. Try to wait before rushing into your child's room. She may be able to comfort herself back to sleep. If this doesn't work, try entering the room and gently letting her know you are there. Do resist the temptation of picking her up.
