Our first Christmas at school and want to gauge normal etiquette. It’s a two form entry school so 60 kids in a year group; my son has received about 5 cards so far, generally with either his name and the sender’s name on, or just the sender. I’ve asked him his top friends of 15 or so and thought could send to just them but am now reading that it’s all or nothing as some children might be left out. He really wants to send cards but I don’t think we’ll manage 59 of them! We just did one and it was haaaaard work - he doesn’t have the energy to try with his letter formation after a full day at school! Would doing 15/60 be ok or is this a huge faux pas?
