MIA-LHR in UC Suites with a 12 month old

We are going to be flying to London from South Florida with our daughter who will be 12 months old. We are currently planning on using VS MIA-LHR, which has the UC suites. We have several questions about this.
While the suites look very comfortable for one person, are they ok with a child on your lap? With the wall, it looks more confining than a traditional first class seat.
Is seats 6A/K the best choice for the trip over with the baby? Or should we pick something like 15D/G?
Do you need to sit in a particular seat to use either the skycot or infant care chair?
Will the skycots work with a 12 month old? Pictures?
What is an infant care chair? Pictures?
Our alternative is to fly Delta's BE, with the more traditional seats.
Thanks for any and all ideas, suggestions, feedback
