Are you supposed to give your guests a thankyou gift at your baby shower?

My baby shower is next Saturday.

I am wondering if it is correct etiquette to give my guests thank you gifts.

I’ve already had thank you cards printed and was thinking of giving each guest a small box of chocolates as a “thank you”gesture.

However I am buying prizes for the games and intend on finding decent things to give, like beauty products, candles etc and there will be enough so each guest gets a prize.

I’ve only ever been to one baby shower and the Mum-to-be did not give out thank you cards or gifts, but she did buy decent prizes for the games.

Opinions?
