They say there will be lots of handwashing etc, but I can't go on the trip myself to make sure my ds does it, and the expert on ecoli (Prof Pennington) said last year thinks all under fives should be kept away from petting farms. Trouble is, ds will be shoved in a class with older children while his class goes off the see the animals, and I will be the most unpopular parent at home (and probably at the school). What do you think?
