Recently my son (20 months old) is reluctant to do anything without me. He cries the whole time if my husband takes him to a park. And earlier today he refused to go outside in our front yard with my husband and daughter while I stayed inside. He also will cry at bedtime as soon as I leave the room, when he normally had been doing fine falling asleep by himself. Is this another form of separation anxiety? How can we deal with this type of behavior?
