I've tried smoothies but if kid sees pulp or seeds of berries, they refuse to eat it. Generally this kid has figured out that there is fruit in smoothies and because there is refuses to try one sip because 'fruit is gross'. I've put various fruits in waffles and pancakes but again, if kid sees fruit pieces no matter how small, won't eat it. I think I'll try pureeing veggies into breads and muffins. This kid won't even eat pasta if it doesn't have either a cream or cheese sauce on it. If I top it with tomato sauce, it will remain untouched. Now that this kid is in kindergarten parents pack a snack for the morning recess at school and it's always quite large and junky. For instance today's was a kool aid juice pack, 2 chocolate chip cookies and a Rice Krispie treat. So it's sometimes enough to pull the kid through til afternoon snack or even home time if I don't serve what they feel like eating.
