Kitz your appointments sound fairly standard. There is no real need for ultrasounds every visit unless there is a pre existing problem, it is normal for the 19 week one to be the last one you have. I find the most important thing to get out of visits is discussing the actual birth. Get an idea of what you want and what they can accommodate you with. Remember to speak up at the visits if you any concerns.

Just remember by the time you get around to the 2nd bub you will probably appreciate the short appointments and not having too many, as you just don't have a lot of time with another to look after.
