I second this. My 2 1/2 year old is the same way. Drop her off, tears in the eyes, 2 minutes later......dad who?
Same with our 3 kids too...cry cry, look around and think "Holy crap! New toys!" Sucks though, you always think they are crying non-stop. Might be able to try it out and hopefully get your money back if the kid won't settle down.
