I know what you mean about the toddlers being much diffrent! Ds hasn't eaten bird doo but he did manage to get a nice mouthful of DOG POOP with bird seed in it!!!!!! OMG I freaked! we were at my sisters house and she had a puppy that had an accident that we weren't aware of and ds found it.... he did get sick the next day and was puking the whole plane ride home - poor kid! but the doc prescribed something to help clean his body from the yucky stuff.
