Hello ...
Having just come across this thread , I believe I ought to give the current ( from July 2016 ) recommendations from H.M. Government. UK
See here: www.gov.uk/government/news/phe-publishes-new-advice-on-vitamin-d
Public Health England , PHE , state that all babies that are exclusively breast fed ( EBF ) should receive supplementation of 340 to 400 IU ( International Units ) of vitamin D per DAY !
The explanation for this advice , is as follows, :
Breast milk , in the UK , ( a Northern latitude country ... at high latitude i.e. over 50 degrees North ) has very small amounts of Vitamin D , in breast milk, generally , on average, has only about 25 IU of Vitamin D per Litre of milk. A baby requires somewhere about 300 to 400 IU per day , depending upon weight. To get that , in practically every circumstance, the baby will need supplementation.
This recommendation has not been forced upon the government lightly , it is the result of much scientific investigation analysed by The Scientific Advisory Committee on Nutrition ( SACN )
IF you EXCLUSIVELY breastfeed your baby .... please take notice of this government recommendation. You will almost certainly need baby drops, UNLESS you supplement yourself with around 6000 IU of vitamin D per day, every day. That supplementation amount would then boost your own milk from 25 to 400 IU of vitamin D per litre.
IF you give your baby SOME formula milk , which normally has been supplemented with 400 IU of Vitamin D per litre, then you can work out what you need to give your baby .
I hope this is a helpful clarification of the often confusing advice given.

PS. I have posted quite a bit here on Mumsnet about vitamin D ,
If you need more information , have a look at some of the threads I have posted re : Vitamin D , mostly in the 'General Health' category, or get back to me.
