Can I just ask why you specially want a rottie? They are great dogs but and there are buts to keep them in a stiuation when although willing you may not be able to provide them with all the time and training they need.
Rottweilers are very loyal, devoted, warm and intelligent creatures.
They are dogs that do not bark unnecessarily and they are proven to be good watch dogs and warn when something isn?t right.
When a Rottweiler is matured, fit and healthy, it is a very calm dog that will love nothing more than to sleep or chew on a bone.
However, there is a downside to Rottweilers. The life expectancy of a Rottweiler is 8-10 years and they do not mature until the age of 2 years old.
Rottweiler health is a concern as they do have a poor immune system, more so as puppies. They are also at risk of hip dysplasia, tearing cruciate ligaments and heart problems as well as cancer.
It is so important to give them lots of proper training and socialising when they are puppies. If you fail to do this they can become unconsciously dangerous as adult dogs.
They play hard and can easily injure someone inadvertently. They also herd young children and other animals, bump, or nip them while doing so without meaning harm.
Rottweiler puppies are generally mouthy and you must teach them that this is wrong ? more so as then tend to have temper tantrums.
Ensure that your Rottweiler is exercised frequently and will need some form of work (obedience, agility, herding, etc). If they become bored or improperly housed they can be destructive.
Reading your op I do not think having achildren is a reason to not getting a rottie but you wil have your hands full with training a young dog that will need full on training and having children - you will lose aany small me time you may have had!
But good luck with your decision it sound like you are thinking through all the options
