Don't you realise, that anything nice a man does for a woman is WRONG?!
It's only fair if she has done the exact same thing in return, and they have both signed a contract to say that they agree with those terms.
And anyway, pregnancy is a doddle, and labour is nothing. There's no way you should get a present for that! And if you do, remember that Section 5a of the Present Charter states that you are only allowed a present if you buy an identical one in return for the giver.
Gifts must be matched at all times. Otherwise you risk all kinds of hell when the Present Police do an audit.
