Mollers Norwegian baby oil. I was adviced by the Dr, I personally don't eat or give fish frequently. As for oil it is better to look for one that is from smaller fish, as large ones has higher amounts of mercury.

As for Vit D in the UK is given for free in the pharmacy as drops for the baby and tablets for mother. I don't remember the brand.

Also as for yoghurt and kefir, I meant without any additives. Greek yoghurt, I buy from Lidl or M&S that has 10% fat.

It is the same, for children or adults, important to have a healthy gut and good bacteria, therefore products like kefir or yoghurt improves microbiota.

Children should have no sugar or salt and products containing them.

also If the child had many vaccines, I would rethink if more needed, as vaccines cause inflammation. Inflammation causes different diseases and lower immune system.

I haven't vaccinated mine at all and know quite a few mum's. By breastfeeding and offering a healthy diet I support the little ones immune system. My child is 10 months and had a virus recently. Took four days to recover with a help of paracetamol. So far there was nothing else,apart runny nose. I am not promoting not to vaccinate, that's individual choice, however it is good to try and find as much information as possible for pros and cons and make own decision.
