DD1 aged 3 and a half has been prescribed third lot of antibiotics since beginning of Jan. Have not given her this lot as they make her sick. I feel the antibiotics are pulling her down. She can't seem to shift these infections and gets better and falls back again. I'm getting worried about her as she refuses to eat and is getting skinny. Any suggestions on what I can do to build her up and help her fight these infections? I give her Calpol to keep her going but don't like giving her this for extended periods of time.
