headcannon that when ast was pregnant for zephyr hiccup was so excited and nervous that he hardly could sleep, so he just, talked with zephyr still in the belly. For hours and hours ab literally everything, like, how was his day, what he did as a chief that day or week, how he loved his wife, how he missed toothless, ideas for future projects, literally EVERYTHING and with details. and every time he talked to zeph he calmed down enough to fall in a completely peaceful sleep without even finishing his own sentences.
all while astrid was sleeping. and she never really had a chance to see the moment because she was always asleep, (i also headcannon that she was pretty sleepy during zeph's pregnancy) until one day she ended up waking during one conversation and found it just so freaking cute that she decided to pretend to be asleep to hear it, and i'm absolutely sure she just fell in love with him all again at the moment
