Query: too bad

My son loved this mobile....but... the batteries keep running out quickly. I mean we were replacing them twice a week. Now the part that turns the mobile (blue ball) sticks. I am going to cut the toys off. My other son (they are twins) has a different mobile by sassy that came will pieces that could be changed as the baby gets older. I wish I would have bought two of those insead.
