Just recently I took Jack to our local Toddler group where we have been a few times before. For the second hour of the session Libby from Smart Talkers came and did some singing and signing with the little ones. I joined in enthusiastically, singing and attempting to remember the signs whilst Jack played in the ball pool and fought for his turn on the ride on train! I thought he wasn't taking much notice of the singing & signing but hoped he would in the weeks to come.
On the car journey home, still with the tune of 'Twinkle Twinkle' and 'Baa Baa Black Sheep' in my head I absent-mindedly began to sing, and Jack joined in! So for the week since then I have been singing to Jack, not to get him to sleep, more of a distraction - he looks at me like I am some kind of freak, but it works - he sits on the potty for more than 2 seconds whilst we reel off 'Twinkle Twinkle', 'Baa Baa Black Sheep' and 'Wind the bobbin up' and when he starts shouting & screaming in the car I just start singing, and Jack joins in.
It's only been a week, but our almost daily singing has paid off, at the weekend he highly amused Grandma with his rendition of 'inkle inkle, ittle dar', and his speech has come on in leaps and bounds, so however bad you may think your singing voice is, don't worry, it really can't be as bad as mine.......and my little one loves it!
