Seasonal variation in infant development

Posted on: March 14, 2013   by  John Cannell, MD


How quickly your baby develops depends on the season of the year and thus possibly vitamin D levels. Researchers at the Hamamatsu University School of Medicine recently studied the seasonality of development of 926 infants born between December 2007 and September 2010.

    My son, a March (13th) baby, was slow to walk, talk and develop social skills…

    We’re talking 28 years ago (and there were other reasons involved regarding his developmental process…)

    But, I digress…Back to Vitamin D!

    Mike always had at least the RDA of Vitamin D, many times much higher…and plenty of sun baking (sans sunscreen) trips to Mexico and Southern Florida in fall, winter, spring summer! These were always part of his life.

    I’m proud to say that he is now a very successful man… an engineer/architect specializing in construction acoustics…it is a highly technical field.

    I didn’t know about the March birth/Vitamin D connection.

    Michael is simply fortunate because I lugged him all over the Yucatan and Quintana Roo…many (many, many) more times than I am sure he wished to travel with me. πŸ™‚

    Everything (imo) happens for a reason, and it is all good! πŸ™‚
