Swim diapers

In case you don't already know, swim diapers should be put on just before going in the water. If you put your child in the swim diaper at home and then in his/her car seat. By the time you get where you're going, chances are, he/she will be soaked. They don't absorb. (Yes. Learned this the hard way.)

Flip side: If you opt to skip the swim diaper and go swimming anyway, your child will have a diaper swollen the size of the floatation devices he/she may have around his/her waist or arms and the walk to the locker room in front of all the parent who know better than you will be at least slightly embarrassing. (Again, learned this the hard way.)

Conclusion - Swim diapers are good to use but only for the prescribed purpose.
