Dean Elgar will lead the side in the absence of Test skipper Faf du Plessis, who had to stay back in South Africa for family reasons.
"I think South Africa have always prided themselves on stepping up to the occasion".
Domingo was speaking ahead of South Africa's first Test against at Lord's. She has since been discharged from hospital.
Moosajee added: "The mother and baby have settled at home, but (Faf) will be unable to make it back in time to take part in the first Test match".
For the new skipper, the perennial question applies for top batsmen who take on additional responsibility: Will the burden of captaincy suppress Root's outstanding early Test batting record of 11 centuries, almost 5,000 runs and an average of 52.80?More news: PM Modi to meet 2008 Mumbai terror attack survivors in Israel

Opening batsman Dean Elgar - who has seven Test centuries to his credit - will lead the team and become the 12th player to captain South Africa since their readmission to global cricket in 1992. "He epitomizes South African cricket to the tee". "Our focus is on the team and getting the team to do well".
As for Elgar, Philander said: "He's got a job to do".
With an injury-hit bowling lineup, seamer Toby Roland-Jones is in line for his debut at his home ground, while Mark Wood hasn't played test cricket for almost two years. "It can play on your mind if you're not used to it". Every time he gets the ball in his hand he seems to want to run in faster, bowl faster and get wickets.
Philander and the bowling unit will have to set the tone for the tourists against an England side that has plenty to ponder in terms of the selection of its starting team. A Test match is a pressure, Lord's is a pressure, your first Test match is a pressure.
