Would i be overwhelming my child by sending him to enrichment class (Music Class, Gym Class ) at such a young age?

Young babies' classes are normally parent accompanied. I feel these classes are good for parent and child bonding and if your baby enjoys during the class, why not? My daugther joined Kindermusik class since 6 months old until she turns 2 years old. She truly enjoyed herself during the class and I also enjoyed myself bonding with her. After the class, we always switch on the music we used during the class and bond together: singing, dancing, and playing musical instruments. For rightbrain class, my daugther joined both shichida and Heguru for certain period. They are parent-accompanied classes too. We used the materials to practise at home and my girl likes it. You can observe your child and if she/he doesn't enjoy the classes, you should try to delay until she/he is much older then resume.
