Well my son is also fussy eater I send him fruits and food which he likes and enjoy please stop giving biscuits cakes bread. Make cutlets fruit pudding
His liking is limited for 2-3 times for a perticular dish or fruit or any veg and very rarely he likes anything... Wat to do... And i agree m also against cakes buscuit
U can give fried cashews kishmish and some fried almonds u mix up these nuts for his snacks box.
U can give him mixed vegetable coconutmilk rice.....just saute clove ..cinnamon. ..cardamom. ..gingarlic paste..onion greenchilli and tomatoes in melteddbutter.....add ur choice of veg mix along with coconut milk and salt..add soaked rice and pressure cook it for 20 mts in simmer....coconut milk s really good fr stomach...include varieties of veg as much as possible...like beans ..carrot ..peas ..cauliflower. mushroom...soya ...etc
