Vit C and Cod liver oil
Mom gave K cod liver oil since 1 yo. She started with the original flavour (yuck!) and she was ok but I was the softie mother who said eeeww, horrible, so I went to buy the orange flavour and of cos, after taking orange flavour, chey who wants original? After some months, I kay kiang went to buy strawberry flavour from Nordic Naturals, die liao lor, who wants orange flavour Scotts Emulsion when you get strawberry Nordinc Naturals? After that strawberry flavour one, I upgraded her to the chewables. So you see, my wallet keeps getting busted. My bad.
With SM, I learn liao - just stick to original if she can take it and stop at Orange flavour AT MOST.
Vit C - I gave Animal Parade multivit in liquid form. Noticed that every time I stopped for a few days, she will catch something. But if I consistently give, she seems more resilient. Waiting to finish the bottle so that I can give chewables.
Nowadays super KS - I give K multivits, DHA chewables and probiotics. This is her daily regimen on top of the medicines she has to take which are Ventolin, Zyrtec, mucosolvan, flixotide (puff) and singulair.
