![]() ![]() She screams if a drop of water touches her head. I thought maybe it was just social gatherings that overwhelmed her, but then she started being scared of things at home as well. When they ask what's wrong, I have no real reason to give them. "She's just tired," I say as I wave my parents off. I mean, I want her to say goodbye and hug them so they feel good and she feels loved, but then I feel bad for forcing my child to do something she doesn't want to do. I have to push her to interact with her grandparents. My dad will ask her if she wants to play outside and she will say she is scared to, with no reason why. They adore my daughter and always try to get her to play. We visit my parents pretty much every weekend. Then her fears started to become routine. I figured she was just being shy and, to be honest, I don't like talking to every person I meet either. "I don't want to talk to that girl, I'm afraid," she told me. Her fears keep multiplying, and I don't know how to handle them.Ībout a year ago, my daughter started saying she was afraid of things. I think about pushing her in to get it over with, telling her to just do it. ![]() ![]() It's not a deep pool and the other kids flail about with smiles on, but she is walled off in her own little twilight zone. Toeing the water at the edge of the pool while the rest of the swim class splashes and screams happily below, she won't budge. I splash my face and feel a moment of cool, but my daughter is shivering in her bathing suit. It's over 90 degrees out, the kind of heat that warps your skin.
