# How to specify an age for the children in the search form?

HBook have 2 different guest types : they are named by default "Adults" and "Children". But you can:

- in **HBook > Search form** : set if you wish to use both of them or not
- in **HBook > Text > Search form** : modify the text of the labels "Adults" and "Children"

HBook does not work with a selection of the children age (as in AirBnb or booking.com). Depending on your needs, you can combine the following options.

### Change the labels

You can use both guest types but change the labels so it says for example "Adults(+16 y.o.)" instead of "Adults", and "Children (2-16 y.o.)" instead of "Children".

<a id="use-only-one-field-labelled-guests"></a>

### Use only one field labelled “Guests”

You can use only the "Adults" guest type but change the label to "Guests".

<a id="collect-children-age"></a>

### Collect children age

You can as well use the extra-services in **HBook > Extra-services** or the details form in **HBook > Details form**, to ask your guests to specify the age of the children.

> If you work with age groups, for example “Babies (Under 2)”, “Children (2–12 years old)” and “Teens (12–16 years old)”, you can as well charge them differently, using the extra-services.
