My missus is 23 weeks and it's been something of a rollercoaster. She had chronic sickness at about week 10, vomiting violently a dozen or so times a day for two weeks, which was quite unsettling, and we had an early scare as well, which wasn't nice.
But things are lot easier just now and we're both fairly relaxed - the 20 week scan showed the baby was perfectly healthy, and we're now feeling her kick and move a lot.
So to answer your question, yeah, it definitely eases, although tensions will no doubt rise again as the big day looms.
Best of luck.
