Nope. Other than to just keep try feeding until things get normal again. It is going to be a dreadful painful and frustrating journey. Don't lose your senses. Get someone else to feed her once a while. A new experience may help.
You can ask for medication from the PD to increase her appetite...
Hi happyjoy2016,
Its that dreadful phase where they like to keep food in their mouth. I remember when my elder girl was at the age of 1 plus, that was what she like to do. Feeding takes hours and was SO SO frustrating. Those days seemed to last forever!
While I can't say when they will outgrow...
