We're off on hols next month. DS1 is apt to escape his travel cot and room at night, and DS2 is prone to tumbing down stairs, which he crawls towards lemming-like. So we thought a portable stairgate would be handy, particularly as we're staying with family in a non-child-proofed house. The stairgate needs to be easy to move between locations, and secure, but it doesn't necessarily need to open. Any top tips/anti-recommendations all gratefully received. Thank you.
