Hello! My DS is now 7.5months old. I started giving him baby rice mixed in his (formula) milk a month ago. I also introduced him to banana strawberry porridge that I also mixed with his milk. He was happy eating and I thought great this is going well, but when I gave him pureed sweet potato mixed with his milk he ate few spoonfuls and when refused to eat more. Since when he has not eaten any solids at all. All he wants is his milk and refusing putting the spoon in his mouth. His first tooth appeared about the same time, could that have caused refusal? Anyone with any tips?
