We started Katie on solid foods the day she turned 4m old! We did this with Will when he was 4m, so we decided to do the same with Katie.
Well, she loves it. She opens her mouth wide when she sees the spoon. She keeps the food in which was surprising as I was hoping for some cute pictures of food all over her face. Maybe that will come later. For now, she seems to enjoy bananas, sweet potatoes and butternut squash.
