In general, yes, it's usually advisable for children to attend, provided they are well prepared and accompanied by a trusted adult who can provide emotional support. Often, with the intention of protecting them, we tend to keep them away from death, the funeral, or saying goodbye. But protecting doesn't always mean excluding. Children are also part of the family; they also had a bond with that person and they also need to understand that something significant has happened. Leaving them out, without explanation or participation, sometimes doesn't lessen the pain but rather adds confusion, a sense of estrangement, or even fantasies more distressing than reality.
The question, therefore, is not so much whether they should go or not, but how to accompany them so that the experience is understandable and comfortable for them . It's helpful to explain to them in simple and clear words what has happened, what a funeral or farewell ceremony is, what they will see there, and what they can expect: that there will be sad people, that some will cry, that there might be hugs, silences, prayers, or solemn moments. It's also important to convey that all these reactions are normal and that they are under no obligation to behave in a particular way or feel a certain way. Some children will want to get very close, ask questions, or participate; others will prefer to observe, stay somewhat apart, or need to step outside for a moment. All of this can be appropriate if they feel supported.
It also helps a lot to give them some choice, whenever possible. For example, ask them if they want to bring a drawing, a flower, read a few words, or simply be present. Participating, even in a small way, is usually more helpful than being left out, because it allows them to place the loss in reality and begin to say goodbye in a shared way. And if at any point they don't want to continue or feel overwhelmed, it's best to respect that without making a big deal out of it. The important thing isn't to comply with a social norm, but to offer them a farewell experience that helps them understand, feel included, and live through that moment with as much emotional security as possible.
