My baby is six months old and is in her fifth week of feeding. It's been slow, she loves banana, avocado, and butternut squash, and I am just confused about how much to give her. If she only has a few spoonsfuls, should I give her something else? I am worried about underfeeding her. And if she eats a whole banana, is that too much? She had a whole mashed pear yesterday and was sick twice today, and was totally off her milk.
