Mary: Yes, in Chicago at Brookfield Zoo... toddler (3) climbed up fence over planter and fell 24 feet... Nursing mother with infant in arms resued child and took to door where the keepers enter.... GREAT story. Interesting information provided on the extensing mothering training this gorilla needed prior to first pregnany as her own mother did not do same.... WHY DO PEOPLE NOT GET IT? ..... Also of note....where were parents/care taker of child when this happened? why did NO ONE watch stop child? None of this is talked about.. Zoo safety is being questioned....... Patricia - i went to this exhibit on monday with 2 -14 yr olds and a 10 year old.. they were always within eye sight and usually within arms lengh of me...-
