You will be amazed to see when your child starts to enjoy singing with others; it can be chanting mantras with grand parents or your cutie pie with start humming nursery rhymes with his elder sibling or he can enjoy singing famous movie song when he hears it.
What you need to know
Your child might have started understanding a bit of lyrics of his favourite song by now.
Mainly you should understand whether your kid is really interested in music or he just enjoys it as part of fun activity. As there is only fine line for parents to understand, if he should get vocal training or he just loves singing as part of his entertainment. It’s better to catch these signs early and if your kid is really showing curiosity towards singing, as a parent you should encourage his skills but it necessarily doesn’t mean in this tender age you must send your kid to any sort of music classes. You can develop his interest by yourself. For e.g. by giving some household items like utensils or empty plastic container and letting him to observe, how they make different sounds. You can always put karaoke in your phone or TV to let them hum the song along with music. So as of now just relax and listen to the most beautiful voice in the world.
