Crying for more chips

It's his first time to eat a potato chips, at age 2 we don't usually allow him to eat junk foods. After we eat the potato chips, he is asking for more and crying a lot but then I told him that it is not good for his age to have more. As if he understand it well, he stop crying and we just play with his new toys I brought from Singapore. I also told him that Daddy bought it for him then he asked "where is daddy?" And he said, "let's go to Singapore, ride an airplane". Ow, he is really a grown up now, I think he became mature when we left him. I promised him that we will be going to Singapore before New year. We really missed daddy, so many crying nights for mommy.
