I'm not sure whether I'll擺滿月酒,it depends on the delivery date. If it is more than one month before Chinese New Year (my due date is 13-Jan), I may arrange it, otherwise it is not worth to do so when it falls into the Chinese New Year period which is much more expensive.
Don't worry. When I was having my first girl, she didn't move too much also (may be I was fatter that time and could not feel the movement well)
This time, I don't gain too much (27lb until now) and I always can feel it's movement. Don't worry too much! The time will pass very very quickily.
