My DH is like this. For his birthday last month, he asked for 'bloke's guide to pregnancy' and 'what to expect when you're expecting'! In fact today when we were out christmas shopping he took me into Waterstone's to point out some more he wants for Christmas
He is being really cute actually, we were at a concert on Thursday night and he keep rubbing my stomach saying 'it's not too loud for the bump is it?'
