Stating on a wedding invitation that you don't want children to attend can be tricky, especially since a lot of people consider wedding celebrations to include everyone. However, there are some ways you can be clear without being rude. Firstly, you may want to consider listing the events at the wedding which are not child friendly so people subtly get the idea. For example, you can mention that the wedding reception will not finish until very late and there will be alcohol available. This is a good approach before stating your 'no children' policy. In addition, you may want to write that the furniture and the equipment at your wedding is very expensive and that you will not be held responsible if anything is damaged by the children.
You need to be firm in your statement but without being rude so make sure you emphasise the fact that it is a celebration for adults only. At the end of the day this is your wedding and the guests should adhere to the choices you've made because if you come across as too passive in your invitation then they may end up bringing their kids anyway. However, you must not write something like 'children not allowed' because this is too blunt and negative which may cause an offence to your guests who have children. If you're resigned to the fact that you won't be able to stop kids from coming you could always check with the reception venue if they have any day care services. This way, the children won't be part of the reception, however guests can still bring their children.
