hi Quickwillow,
welcome to the forum..
just make sure u've got all the documents needed for their application (fiancee and her child) and everything will be ok..
we've got lots of threads/posts with the same situation u are right now and so far most of them are fortunate and happy now living with their love ones here in the UK..
Goodluck and if most of us managed to do it, I am sure u also can..
