Lightly cook hard food like carrot or pear and cut into fingers for her to pick up. Mash some pumpkin and give her the bowl and a spoon. Picking up peas and blueberries will help develop fine motor skills. It's not all about eating. There's so much learning. There will be mess. Sometimes you'll wonder if she's even ingested anything - but her poop will tell you good luck.
