Query: Cute, but should run longer.

My son likes this mobile, but the wind up mechanism is way too short! It only runs for a minute or two on a full wind up and then my son gets upset because it shuts off, so I am constantly running back into the nursery to wind it back up. And since we live in a 2 story house with bedrooms located on the second floor, this is completely impractical. My son doesn't spend a lot of time in his crib during the day, but I really would like a better functioning mobile for those times when I need him to be safe and entertained while I do a household chore. It's cute though and matches the bedding set I purchased. However, if it wasn't for the fact that I don't put my son in his bed a lot during the day, I would have returned this item shortly after I used it for the first time. I would have gladly paid a few dollars more and given 5 stars if this ran on batteries instead.
