At the initial periods, New born and Baby Photographer from London, Sandi Ford had to lie in wait with camera on hand for the babies to make broad smiles as a sign of pleasure, and then make shoots catching the condition. Having taken frequent snaps, he has now learnt the signs and symptoms that serve as harbingers of the upcoming smile of the baby. So, without long waiting, he is able to take shots of such smiling moments. By experience, Ford says that some babies are more smiley than others, and that some tickle on the lips or nose would trigger smiles. The technique is really effective, though some ignore them as of no significance.
