This might sound a silly question but I'm going to view a property later and have to take some measurements and need both my hands free. I've got my 18 month old dd with me in her pushchair. Should I leave her downstairs in the hallway with the agent for 2 minutes to go upstairs to a bedroom to measure something? The agent is a female whom I've met before, who says she's a mum. The alternative is I get her out and carry her up there but then she will want to run everywhere and touch everything...
