i have 擺滿月酒 for my first baby too!! i invited some close friends and family la, it was around 6 tables. The atmosphere was OK la!
I think the main purpose of 擺滿月酒 is to let ppl share the joy with you together, and it is only one way of showing it!! Any other forms is also OK gei.
But i want to remind every mom that don't miss this 擺滿月酒 chance to give thanks to every mother lor. After being a mother, i really feel that my mother/grandmother, and all the mother are great la..>They are soo sun fu to raise us up....
And i think the meaning of 擺滿月酒 is giving thanks too!!
