How much childproofing do you think is reasonable to expect grandparents to do? Just spent stressful weekend with DD (11 months, crawling and cruising) at PIL trying to keep her away from Wedgwood china on low TV unit, cactus with prickly spines on floor, unidentified houseplant on floor, modem cable trailing across living room and display unit with decorative plates just waiting to come down if bumped...as well as ungated stairs, medicines in low kitchen cupboard etc. Admittedly we don't visit that often due to distance but AIBU to hope that there might be a little preparation for the mutual protection of DD and grandparents' house?
