When I'm home, I only do fruits in the morning with hash browns. She is normally full after, and she eats what we eat for dinner. But with his mom, say my daughter wants food all day.
Oh, is there a chance she's feeding her differently than what you would normally give her? Also with the teeth brushing, I would bring it up if you haven't the importance of brushing her teeth. I'm the same way with my baby, I'd hate for her to have to deal with cavities!
How old is kiddo? Those cherry tomatoes are whole so she is like 4? I don't really understand, what hours of the day does MIL watch your kid? Why do you not know what she's eating? Ask MIL to record it if you want.
Do you think baby is truly still hungry? From the food I see on her tray, those are nutritious things but they're not very fully, the oranges and tomatos are fresh fruits but not much calories. The rice crackers are good "occupying snacks" but are empty calories, and the avocado has healthy fats but it may not be enough. Kids need high fat diets for proper development, if she's still eating or asking for it, she's probably still feeling hungry. When my baby is fully satisfied, she'll refuse to eat any more. Now some kids will keep eating but not typically. Protein is important too but not to be overdone. My baby eats food and is breastfed as well but I offer 3 meals a day and snacks in between. Toddlers graze all day but they need it!
