This is a kinda-gym that also incorporates musical activities and toys and one-on one consultation for your child/baby by the physiotherapist who designed and runs the program. She is a very experienced owner/operator who is really really good with the babies.
It took a few weeks for my 6 month old baby to warm to this, but after a few sessions he absolutely loves it. His favourites are the parachute and the air-gym, which the parents can go on with their children.
I really highly recommend this children baby/gym to anyone.

Approximate cost: $22 per session
