This is my first post on MN. DH and I are taking DD(28mths)and DS(10mths)to visit my sister in Notting Hill/N.Kensington. We are flying from N.Ireland and then hoping to spend most of the long weekend around her local area as we need to use a double buggy (P&T)and are not sure of what this means for travelling around in London. She lives in a child-free world! Any advice or suggestions for activities and/or places to eat etc would be most welcome. We don't mind what we do, just all want to hang out together and keep the kids as happy as poss!
