I had my second baby last Autumn and only just started needing a swim option this month so I got a Babykicks Swimmer it cost less than a large package of Swim diapers (Its $13.95 at BabyKicks Website)
There are 4 sizes of Babykicks Swim Diapers
available. The size I got was large (which starts at 21lbs but My baby is nearly 20lbs so I decided that size would work best for us) The diaper is very attractive with a Gender Neutral print that has cute crabs, live preservers, light houses,fish and anchors on it. I love that it can be easily pulled on or unsnapped at the side in case of a big poo mess.
The first time I took baby in the pool we used a regular diaper with ot and insert and it was difficult to put on him at the pool, the babyKicks swimmer was very easy to pull on and take off after we were done.

Over all I am happy with the way the swim diaper from Baby kicks is preforming for us. I am nopt worried about washing it because unlike its disposable counterparts it is meant to be washed. I intend on using it for this and next summer as long as it fits him we will also try it when we get to potty learning. Its pull up design and water proof cover will make a great addition to our training pants collection!
I would suggest this as an affordable option to people in the summer who want a cute water diapering option!
