No, never gave my baby any of that, no vitamins or anything other than what they got from formula and food. He is 13 and 6’1 now and basically has never had any health issues.

Haven’t but try to give her yoghurt or yakult if gastro issues

Never heard of giving probiotics to a baby, they would be getting all they need through breastmilk or formula, if older they can get it from fresh wholefoods, keeping them away from sugar is the key.

Only when she was put on antibiotics

I gave my 18 month old probiotics for a while after she started daycare as she kept getting gastro all the time seemed to help it was recommended by the pharmacist

no nothing extra than the yoghurt

I did when he was sick or had thrush/yeasty nappy rash.

No, but he eats yoghurt everyday, a good organic brand
