A good lullaby is undoubtedly your best ally in putting your baby to sleep. Trust me on this, you will automatically devise one when you need one.
If you are from Kerala, then you would have probably heard the
'Omana thingal kidavo' lullaby. You can listen to this lilting lullaby
here (use IE). Its one of the hugely popular lullabies and is no doubt elegant, written as it was for putting the prince Swathi Thirunal to sleep. This is what my wife sings to put our baby to sleep.
Given my musical talent, rather the lack of it, i use the much simpler 'Harae raama'. Surprisingly my son likes it a lot. After some experimentation it appears some of the syllables can be stretched for additional impact. So instead of 'Harae raama', i sometimes use 'Haraeaeaeae Raaaaamaa'. So my lullaby is simply
Harae raama harae raama
raama raama harae harae
Harae krishna harae krishna
krishna krishna harae harae
My mom on the other hand uses '
Yaadevi sarvabhudeshu'. You may or may not have heard of it. Its a very nice hymn with a good meaning. All the stanzas look almost the same, one word is replaced to give different meanings to each stanza.
Yaadevi sarvabhudeshu
vidya rupena samsthithaah
namastasyai namastasyai
namastasyai namoh namaah
Here
vidya can be replaced for ex with
budhi, matru, shraddha, shakti etc.
I think the power of these simpler lullabies is in their words like harae, namastasyai etc which have the right tones for inducing sleep in babies. And when repeated many times, they soothe the baby to sleep (hopefully).
My wife's mom uses some wildly funny lullabies. For ex
Ambili ammaava thaamara kumbilil enthundu
kumbittiruppano maanathe komban aana purathu
And if our son is a bit irritated or is crying his heart out with his eyes closed (often at midnight and probably after some nightmares) a resounding & reverberating '
Om' stops the wailing on its tracks.
