keep offering her foods. she will eat when shes hungry. if you want to wean her from nursing cut down the nursing sessions to certain times a day and only let her hurse after shes eaten a few bites of food.
hang in there momma,
my kids both were on the toddler fat diet ( where i was to offer them everything they tell you not to eat if you want to lose weight, i had to butter their bread, butter their veggies etc. ) because when they were 12 months old they went thru the not eating phase and dropped in percentiles for weight.
as long as shes getting nutrients in her (from breast milk or food) she will be fine.
