Reply To: Is there any known connection between prematurely closing of a baby's fontanelle and supplementing with vitamin d while breastfeeding (4000 IU a day) and also giving the baby vitamin d (400 Iu per day)?
No there is no connection.
One of the signs of rickets is “•Soft skull bones and a delay in the closing of the soft spot at the top of your baby’s head (the anterior fontanelle)”. I assume you are talking about the anterior but maybe/or also the posterior fontanelle.
Was this confirmed by x-rays and or scan. I ask because one website said that “Occasionally, the scan will reveal that the soft spot has not really closed and is just difficult to feel.”
