Hi there, my son has been with the rollers class since he was 8 months (he is now 13 months). I'll say the experience was good because you could really tell that the teacher really enjoyed being with the babies. One down side is that most of the time, helpers take the baby to class. I personally like to take my baby to class because the experience we share together is priceless. With that said, I haven't been to other playgroups to really compare. My baby goes to gym, music class and swimming as well.
