Re: 15-month old refusing solids
At this stage, babies are still capable of being well-nourished by consuming mostly breastmilk with a few additional solids. Their eating patterns are inconsistent. Some days they will eat a lot of solids, other days nothing or next to it. And their food preferences will be all over the map. They may love beans (or whatever) one day, and then turn up their nose at them the next.
It sounds like you are taking the exact right approach. Put a variety of healthy solids in front of your LO, and let her choose how, when, and how much to eat. She will eventually discover that she likes solids and will start eatngi them, I promise!
