Hello everyone ? It's been 6.1 months and I want to start introducing solids???? I have read a lot about it and thought: there's nothing complicated here! But when it came time, I felt like I forgot everything and didn't know anything: where to start, how much to give, etc. Could you please tell me how you started, what you gave, and after how long did you introduce new products? I'll say right away that I consulted with my pediatrician, she told me to give mashed potatoes, then add carrots, then try other vegetables and cereals, but something didn't quite work for me ??‍♀️ I want to read how it was for you ?
