Hey,
Everyone's experience is different so try not to compare to others.
Every university degree can be hard however, you will succeed if you put in the hard work.
The lecturers are preparing you however, if you really enjoy the course and want to be a child nurse i would stick at it.
Child Nursing is a great career with lots of opportunities to progress in the future. It is also a very rewarding job where you will make a difference.
My advice is to have a think if you really want to be a child nurse and to see if you can picture yourself being a child nurse in the future. It will be hard and there will be bumps in the road however, if you are really passionate definitely stick at it!
I hope this helps
