when will you start sending your child for classess ? do you think they learn much when they are so young? Will it cause stress to them as some of my friend send child to classess as young as 6-8months

It really depends on what u want for your child and what your child enjoys. We have sent our kids to different trial classes before 1 year old, its not stressful for them as they basically won't listen to what you want them to do so we ended up sending them to kindermusik classes where they can play and have fun at the same time.
