Feeding aversion???

Hi mummies! Please help.. I started my 6 months old on solids after getting the green light from PD and she is also able to sit up unassisted and looked ready. The first 2 weeks she was okay took a few spoons and drank abit of water. But now she is on a feeding aversion. Completely rejecting solids , water or any form of feeding. Even ebm with bottle feeding is rejected. She drinks well when I latch her. I am returning to work in 2 weeks time and she has to eat and be bottle fed by the helper. Her PD is so concerned about her weight as it has remained the same since 4 months and wants me to give her more solids. Hitting milestones well and diaper output is good but no weight gain at all. I am extremely worried and upset.. I tried making meal times as fun as possible, let her play with the food etc but all fails and she just cries murder. She only wants to be breastfed and nothing else. Anyone experienced this? Please share what you did.. Many thanks!
