HI Dinny.
One thing I'd like to point out is that not all colleges have the same type of course layout. I'm assuming it is still the same where I trained, but there we had x amount of weeks in college and then x amount of weeks on placement. This is better in terms of continuity, but can pose more of a problem for childcare. If however, DH is able to do nursery drop off and/or pick up, it wouldn't be too big a problem. And everywhere is becoming more and more flexible with shifts, such as long days, which means most weeks you only work 3 shifts. Also a mixture of nights and weekends would be required, which I hated as a single person but with a family I can now see to be desirable .
I really hope I am not sounding overly negative, but I just wanted to add, that although gaining experience as an axillary imo, is pretty much essential to check you will love the job, I am not so sure that you could rely on such a position to provide a secondment opportunity in the short term. There is, IME much competition for places and I think although worth a try, would be perhaps overly optimistic to rely on this.
Your local hospital will have a list of positions available. Or if you have no idea at all which area of nursing appeals to you I always reckon an excellent starting place is the hospitals nurse bank. Here you will be able to choose your shifts on all the wards in the hospital as they become available. You say when you can work and you can choose which shift you fancy. The only drawback with this type of work is that you may get cancelled a fair bit, with no monetary reimbursemant however late they cancel you!!
In most cases the hospital will put you into training for basic life support, first aid, etc, and provide you shadowing shifts on friendly wards to show you 'what' to do. A great confidence builder.
I don't think you will be an auxillary for long. It is a nice starting place but you are as CM said, a bright lady and you will see a great many things that you will want to do differently and often the best way to achieve that is to become a fully trained nurse.
Also worth mentioning at this point then that most universities recruit for nursing twice a year, so get a few months experience apply, and I'm sure you will do brilliantly. If you can afford to earn around 6k, I'd do it that way to ensure you achieve your potential quicker.
I HTH and I have sounded really negative.
