My 7 month old who is on a good EASY 4 hour schedule has started to refuse her bottles of formula or only takes 1 oz at a time. Some days I only get 5-7 ozs of formula into her all day. She will take little sips of water, less than 1 oz for a day. We have tried different bottles and different sippy cups. She east 1oz cereal and 1 oz fruit for breakfast. 1 oz veggie and 1oz fruit for lunch and same for dinner. I try to give 4 bottles daily! This is the fourth day and I am lost for ideas. Please help. Her bowel movements are difficult for her to pass lately (due to lack of fluid) and much firmer than normal. She doesn't appear to be ill in any way. HELP!
