How to get your mom to buy you the toy you want
Choose the right time to ask for the toy.
It is important that you have this conversation at a moment when your mom has time to talk to you about it. Avoid bringing it up when she is too busy, because she is more likely to say " no " so that she can get on with what she was doing.
If you choose a moment when she has some time, you can have a longer and more productive conversation. Don't ask in the morning when she is getting ready for work and you have to get to school.
