I wore a "baby on board" sign and stood up in a skype conversation to tell my folks about dd, DH was there for testing.
DS I tested by myself and rang him to say "I just wanted to tell the father of my children that I love him" blubber blubber.
It's so much fun.
You could get daddy merchandise. Some very cute stuff around. Go on a date and present him with a pressie. A reality tv couple, maybe farmer wants a wife? Got a box and put three peas inside as they had always said they were two peas in a pod. Cute... Apparently so the woman's mag told me (must be true) he know straight away.
Keep daydreaming! I too dreamt of it for a long time and it was even mote awesome than id dreamt.
