Of the things a child can be taught to say, the request is the one that pays immediately. Naming a banana is useful later; asking for a banana changes the next thirty seconds. That is why manding is normally the first target in a language program, and why it is the one worth getting right at home.
The four conditions
A request needs all four at once, and it fails quietly when one is missing. This example builds around a wanted object, because it is the easiest case to picture — but a mand can just as well be a request for something absent, for help, for a break, or for information, and the same four elements still apply in a looser form.
The child wants the thing, right now. Motivation is not a mood — it is specific and it expires, and it has to be checked in the moment rather than assumed from routine. A child who has just eaten a full meal often does not want a snack, but that is a common example, not a rule — the same child might still want one particular favorite food. A request taught without that want actually present is being taught without the thing that makes it a request.
The thing is present, or nearly. In view and slightly out of reach is a common arrangement for a short, deliberate teaching moment — not a general rule about restricting a child’s access to their own things — because it makes the want visible and the request useful in the same second.
There is a beat of waiting. If the adult hands things over before anything happens, nothing needs to happen. Pause for a moment — long enough to leave room for a response, short enough not to turn into a test. That pause is the child’s chance to ask; without it there is no request to reinforce.
The consequence matches what was actually asked for. Not praise, not a sticker, not “good asking” while the thing itself — a cookie, a hand of help, an answer — stays out of reach. The request works or it does not, and the child finds out immediately which.
Form comes last
Parents ask whether to hold out for a word. Early on, no. A point, a sound, a picture handed over, a hand placed on yours — any of these is a request, and any of them is enormously better than the alternative, which is usually crying or grabbing.
Shape the form afterward, gradually: accept the approximation today, accept a slightly closer one next week. What you must not do is refuse the request the child is capable of making until they produce one they are not. That teaches that asking does not work, which is the opposite of the lesson.
The behavior it replaces
Almost every child already requests in some form. A child who pulls you to the fridge is usually requesting; a scream at the cupboard often is too, though not always — the same behavior can come from more than one place, and it is worth checking rather than assuming. The behavior everyone wants to reduce is often the only request the child has available.
Which means teaching a mand is rarely adding language to a silent child — it is usually giving an existing request an easier form. When it works, the older form tends to fade because it costs more and works no better. When it does not fade, the usual reason is that the old form still works faster, and that is worth checking before concluding anything about the child.
Anything involving distress or challenging behavior belongs with your Instructor or a supervising BCBA. Guessing at why a behavior happens is where home practice can make things worse rather than better, and it is the one part of this that is not a family job.
