If you decide to refuse him in anything, then be sure to explain to him why in this case “impossible”. Tell your baby that you love him very much, but you just don’t have the opportunity to buy him at the moment or that you are upset not good deeds. He must clearly know where the border between “can” and “impossible”! Do not make a mistake when today you told the child “no”, and tomorrow you will say “yes” at his request.
