I'm getting really concerned now. Day three nothing to drink. She won't even let me put a medicine syringe in her mouth. She holds her mouth closed tight and pushes me away and turns her head. She arrives at 8:30 and leaves at 5:30. She eats puree but will not drink anything! She's losing weight and only drinks when she's home. What should I do? What should I suggest to her parents? She's already an underweight baby and has regular weigh ins. I'm scared for her well being.
