Children Rhymes

Thanks for the YouTube as it keeps my kid entertained. I keep a play list of all his favourite rhymes and i play then when ever he wants. Really these rhymes are very helpful if i want to feed him. I also bought few Telugu Cd's from India of this kind. I am not sure what makes them to get attached or addicted to those may be the cool tunes or actions makes them to stick to those. They really enjoy these stuff and every time he gets involved in it as if he was watching them for the first. Recently one of my friends said that it is not a good idea to get them engaged with the laptop as it may affect their eye sight. I really didnot realise this until she said though i was aware of this fact. I decided to not to play them from laptop but some times i could not escape from his thoughts...
