Might be a bit complicated since neither me or the wife would be living in the UK after sending the baby over~ And she'll be at my parent's house
I was going to suggest a dependent visa since she is dependent on you etc. but i'm not sure how that plays into it if you're not here either.
In any case, you'l likely need to show bank statements, employment letters, pay slips etc to show that you have enough funds to support her. Again, not sure how it works if you aren't here either.
