Recently started using the larger size. Must say that I prefered the open flat design which you get in 0-6 and 6-12 months. However still a good buy and relatively easy to put on. We are making very good progress in the lessons as my baby is always warm and happy to stay in a long time.
Good quality and easy to put on. I would recommend this as water can be cold at the swimming pool even for adults. Being warm in the swim class is the key to a fun successful experience!
I took my baby swimming without a baby wetsuit and she really felt the cold, would definitely recommend especially for younger babies.
