Flying from Ottawa to Kuwait via London Heathrow

I will be travelling in 3 weeks, going from Ottawa to London Heathrow (LHR), and on to Kuwait.

I arrive at LHR Terminal 2 and, after a 6-hour layover/transit, depart from Terminal 4 for the flight to Kuwait.

How do I get from Terminal 2 to Terminal 4 and will I need to go through customs and immigration?
Is there a place we can rest whilst not leaving the airport?
The entire trip was booked via Air Canada; the first leg is on AC, the second on British Airways. Will I need to claim my baggage from AC, or will it be checked through?

I am flying with a child and I haven't traveled in a while.

Luckily, Heathrow's website has an excellent tool to take the guess work out of this.

I used March 9 as your travel date, flight AC888 from Ottawa and BA157 to Kuwait.

As per the website, you'll have to:

Follow the signs for connections.
Take the free shuttle bus.
Go through security screening.
Wait for your next flight.

Its been a long time since I've been through Heathrow so I cannot comment on the rest areas, but from what I know there are individual seating pods and lots of seating areas that you can avail.

You will not need to re-check your bags.
