Can someone please help me? My husband insists that there is no difference between the top shelf and the bottom shelf in a dishwasher despite the fact all the baby/toddler utensils I buy all say to be washed on the top shelf in the dishwasher. He said until I can explain why this is he will continue to wash dd's (2yrs old) goodies wherever there is a space and frankly it's beginning to p*ss me off. Before I bring in the marriage guidance people, can any of you give a suitable explanation for my stubborn (not D) H. Thank you!
