Solid foods

Hi ladies. Charlotte and I are having a rough go with solid foods and i don’t know what to do any more. She hates them. All of them. I recently got in trouble from the pediatrician because she wasn’t eating very many solids and I have tried to be better about it. But it is a struggle. She spits and screams and gags. The minutes I put her in the high chair she is screaming. Help me!
