My Wife and two year old daughter are out with me here in NZ. The accommodation CTC provides is not suitable for kids so I am renting a place 5 minutes from the training centre. CTC have been very supportive with my family being here and I haven't had any problems living away from the other cadets.
Yes, you have to remain focussed, but there are plenty of times to relax and enjoy being with your family. Coming home to see my daughter's smiling face after 6 hours of ATPL Law lectures definitely helps!
