I purchased a pack of these panties for my two year old.  For the most part, she is potty trained but still like to keep her in training panties when at daycare.  I was excited to receive these panties so quickly!  But when I put them on her and she was walking around with them on, we could hear to sound of plastic.  These panties have plastic made in them which is loud and not to mention hot!  She wore them for about an hour and took them off complaining that her bottom was sweating.  Of course I cannot send panties back so I ended up tossing them in the trash after a week.  (If you do decide to purchase this, I would suggest sizing up a size).
