Fel: it depends, i alr told my mum, for my uncles, aunts and cousins, i will invite. for the kids part, those 4 n below im ok, those that require one seating alone, i wont invite, unless its only 1-2 kids. cos huh, some relatives, eg 2 adults n 2 paying kids, they maybe only bao for themselves but kids nvr bao. =X one very good eg is one of my uncles, he has 4 children, and 11 grandkids. their whole family go nvm, still bring their maids along. but they only bao for the adults (kids n maids nvr bao), they alr take up 2 tables lor! this was what happened to one of my other relatives wedding. super -.-"""" thats why i tell my mum, i will only invite the adults. n MAX i give tt uncle is one table only.
my sis wedding is this weekend, she jitao tell my parents to inform all my relatives its an all adult event only, cos her she only intend a small n cosy wedding of 15 tables. but ultimately, it is up to u cos your mum alr informed u. but somehow, i feel that u can communicate with ur mum again? tell her u will invite the "elders/seniors" in the family, but the juniors can skip?
