Will I hinder development if I don't go to any?
I play with her (as in silly faces/voices/expressions), play music and sing, give different textured object to touch and I like to think that, without going overboard, my baby is visually stimulated (though with winter approaching we'll be staying indoors more).
I read that the most important development happens in the first year (DC is now four months).
Do most people go to these classes (sometimes I feel like I'm the only one not going)? I just don't really fancy it.
