They didn't find anything at the doctor. I am beginning to think it is behavioural. She won't sit in her booster seat to eat, but will eat if I let her stand in the kitchen with me and feed her or give her water and milk. I gave in and let her do that yesterday as I was concerned that she was sick and she hadn't eaten or drunk anything all day. She is eating at home, though the mom also has a problem with getting her to sit in her seat (this is apparently new). I cannot allow her to eat and drink standing up or walking around etc. My thinking is that I should just stay firm as I do for all the other kids and put her in her seat and if she cries she cries. What would you ladies do? She was actually playing a bit today and walking beside the stroller when we went for a walk...she doesn't seem sick.
