My daughter is 2.5 years old. She has always be clingy to me but it has gotten progressively worse since January. She started pre school 2 days a week. She has no problem when I drop her off and really enjoys being there. However, since she started school she is crying hysterically for me at bedtime. Sometimes for hours with us going in there several times to calm her down. She will do this until 10 pm sometimes. It's exhausting and we are at our wits end with it. We assume it's because she has separation anxiety from me as she doesn't even like when I am away from her to go shower. We're stumped, exhausted and frustrated by the situation. Plus we feel terrible that she is so emotional and worked up, like this. Is this just a phase, is it normal separation amiety stuff? Any insight is welcome.
