Picky Eater

My son used to have big appetite up until he turned 26 months, he is 28 months now. He suddenly became a picky eater and his appetite was so erratic. He didn't want to eat the food that he used to love. He was trying to assert independence like if I asked him if he wanted to eat this or that, his immediate reply was 'No'. I still make snack exciting for him. I let him choose a cookie cutter and encourage him to cut the sandwich himself. He is always excited to do it, but after the cutting is done, he will just take a bite then will push it away. I began to worry about him not eating enough or not getting the nutrition he needs, although he drinks a bottle of Pediasure a day. But when I learned that this is just a phase and will come back to normal soon then I rested my case. Two days ago I cooked Tinolang Manok (Chicken Stew) and gave my son a bowl with rice, and miraculuously he ate them. Wow, I guess the 'hungry' days are over for him. So today I made Pancit (Noodles) and he had quite a lot too. Knock on wood, I hope this will be the start of his appetite back to normal again.
