Hey ladies, my Vit D was low during my PG with DD2, she is having pentivite every day, the reason i was given was that children themselves do not obtain vit d from being outside in the sun like we do until after 1yr of age, therefore they get their Vit D through us during PG and through the supplement we take while BFing... If we are deficient or low they can be too.. Vit D helps with calcium also i believe and is a requirement to assist with bone development.

HTH, not sure how accurate but this is what the hosp and my GP have informed me.
