Aiyoh, 11 months is such a tricky stage, a few of us mums go through this too! Have you tried offering finger foods and letting dia makan sendiri, sometimes kids prefer that over being spoon-fed, or maybe try mixing foods she loves with new things to make it more menarik. Definitely best to check with your paediatrician to rule out anything, then maybe tweak her meals, more calorie-dense stuff like avocado, egg yolk, and full-fat yogurt helped my friend's baby gain weight faster. In the meantime, offer frequent small meals and snacks throughout the day la, jangan pressure her too much during mealtimes
