here in the US most baby showers have games and/or activites, snacks and a cake, and everyone brings gifts usually from the moms registry of baby items. its a lot of fun. it used to be primarily women, but nowadays its widely accepted for couples and families to attend. i havent heard of too many of them that were surprise showers. the mom is usualy involved in planning somehow so she can provide where the registry is and the date/time she can be available for it at the very least.
my OB today went over what to expect about preterm labor and postpartum hemorrhaging since i have an increased risk of both. it was kinda scary hearing what all could happen, but i guess its best to know and be prepared just in case. i have another scan in two weeks though so thats a huge plus
