cratchit, unless you and baby are non-Caucasian, NO need to supplement IMO if you give your baby a balanced diet of solids past 6 months.
I say this because experts recommend that non-Caucasians living in cold, dark climates like the UK, supp. their bf babies with vit. D. The best source of vit. D is sunlight and darker skinned mothers and babies tend to need more sunlight than fair skinned ones. For example I read that in Canada excl. bf babies of darker skinned mothers are given vit. D supps by the health service there. For some reason this is not done in the UK.
I went through a period of doubt at 6 months because in various other countries vit. supps. are recommended for bf babies. I wondered why the NHS doesn't do this, asked GP and HV and got silly replies, so did my own research.
See kellymom.com and la leche league website which give details of scientific research.
I am white Caucasian and so is my baby (excl. bf until he was 6 months and still bf at 20 months). Decided after doing my own research that supps. are not necessary because I give him the natural stuff instead. The two main things that breastmilk will run low on past 6 months are:
- iron and zinc - I started him on meat very early on at around 7 months (as recommended by research on LLL website) - I still give him a bit of chicken or lamb every day
- vit. D - I make sure he gets plenty of natural sunlight - even when he was a tiny baby I would take his trousers off and take him out into the garden for 20 mins. of direct sunlight PER WEEK. You have to weight this against the risk of sunburn etc, but look at it another way, 3 mins. of direct sunlight is recommended (i.e. 20 mins. per week), 3 mins. is very unlike to cause a sunburn. Apparently 20 mins. per week is all that is required to absorb enough vit. D for a baby or toddler.
Of course vit. D plus other vits. and iron are all added to formulas, but as always formula is a very poor substitute for mother's milk and the benefits of bf past 6 months (and for as long as you wish) far outweigh the reduction in certain elements of bm past 6 months. In fact calcium and vit. D and iron which exist in bm are far better absorbed by the baby's gut than artificial supps.
Other vits. like A, C and E can easily be given in the babies natural food.
Good luck whatever you decide !
